The speed of the truck before the collision was 3.2 m/s.

The speed of the truck before the collision can be determined using the principle of conservation of momentum. Momentum is the product of mass and velocity. Therefore, the momentum of the truck-car system before the collision is equal to the momentum of the truck-car system after the collision.
Let us assume the speed of the car before the collision is zero. Then the momentum of the truck-car system before the collision is equal to the momentum of the truck alone. This can be expressed mathematically as:
Mbefore = MtruckVtruck = (6,300kg)(Vtruck)

Mafter = (6,300kg + 1,000kg)(2 m/s)

By equating the two equations, we can solve for V, which gives us a value of 3.2 m/s.

Therefore, the speed of the truck before the collision was 3.2 m/s.

The phase line of the logistic model indicates that any solution approaches the equilibrium solution p(t) ≡ a b as t approaches infinity. This is demonstrated by the behavior of the arrows on the phase line, which point towards the equilibrium point as time progresses.

The logistic model is a differential equation that describes population growth with a carrying capacity. It is represented by the equation \(\frac{d}{dt} p\) = k × p × (1 - \(\frac{p}{a}\)), where p represents the population size, t is time, k is a growth rate constant, and a is the carrying capacity.

The phase line is a visual representation of the solutions to this equation. It consists of a horizontal line representing the population equilibrium solution p(t) ≡ a, and arrows indicating the direction of change for different initial population values.

As time approaches infinity, the arrows on the phase line point towards the equilibrium solution p(t) ≡ a. This indicates that any solution to the logistic model, regardless of its initial population value, will eventually approach the equilibrium population size.

The population growth will slow down and stabilize around the carrying capacity a. This behavior is a result of the logistic growth pattern, where population growth rate decreases as it approaches the carrying capacity.

The magnification of a person's face when it is 0.155 m from the vertex of the mirror is +1.76.

To find the magnification of the person's face when it is 0.155 m from the vertex of the mirror, we can use the mirror equation and magnification equation.

1. First, let's define the variables:
f = focal length of the mirror
R = radius of curvature of the mirror
u = object distance (distance of the face from the mirror's vertex)
v = image distance (distance of the image from the mirror's vertex)
M = magnification

2. Calculate the focal length (f) using the radius of curvature (R):
f = R / 2
f = 0.718 m / 2
f ≈ 0.359 m

3. Use the mirror equation to find the image distance (v):
1/f = 1/u + 1/v

4. Rearrange the equation to solve for v and substitute the values of f and u:
1/v = 1/f - 1/u
1/v = 1/0.359 m - 1/0.155 m
1/v ≈ 2.785 - 6.452
1/v ≈ -3.667
Now, we can find the value of v:
v ≈ -0.273 m (the negative sign indicates that the image is virtual)

5. Calculate the magnification (M) using the magnification equation:
M = -v / u
M = -(-0.273 m) / 0.155 m
M ≈ 1.76

The magnification of the person's face when it is 0.155 m from the vertex of the mirror is approximately 1.76, which means the face appears 1.76 times larger than its actual size. The positive value of magnification indicates that the image is upright.

The angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

To determine the angles θ and θ' in the given scenario, we can use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the media involved. Snell's Law can be stated as follows:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Where:

n₁ is the refractive index of the medium of incidence (in this case, air with a refractive index close to 1),

θ₁ is the angle of incidence,

n₂ is the refractive index of the medium of refraction (in this case, linseed oil with a refractive index of 1.48), and

θ₂ is the angle of refraction.

Let's solve for the unknown angles θ and θ' using the given information.

Given:

Angle of incidence θ = 1°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of refraction θ₂.

Using Snell's Law, we have:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

sin(θ₁) = n₂ * sin(θ₂)

Plugging in the values:

sin(1°) = 1.48 * sin(θ₂)

We can now solve for θ₂:

θ₂ = arcsin(sin(1°) / 1.48)

Calculating this value, we find:

θ₂ ≈ 0.688°

Now, let's determine the angle θ'.

Given:

Angle of refraction θ₂ = 0.688°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of incidence θ'.

Using Snell's Law, we have:

n₂ * sin(θ₂) = n₁ * sin(θ')

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

n₂ * sin(θ₂) = sin(θ')

Plugging in the values:

1.48 * sin(0.688°) = sin(θ')

Solving for θ', we find:

θ' = arcsin(1.48 * sin(0.688°))

Calculating this value, we get:

θ' ≈ 1.988°

Therefore, the angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

\(-24.5=-12.1+-9.8t,\\-12.4=-9.8t,\\t=\frac{-12.4}{-9.8}\approx \boxed{1.27\:\mathrm{s}}\)

The amount of salt in the tank after t minutes is 25 + 0.475 t, in kg.

We can solve this problem using the concept of mass balance. The rate of change of the amount of salt in the tank is equal to the difference between the rate of salt entering the tank and the rate of salt leaving the tank.

Let S be the amount of salt in the tank at time t, in kg. Then the rate of salt entering the tank is:

30 L/min × 0.02 kg/L = 0.6 kg/min

The rate of salt leaving the tank is:

\(\frac{25\ kg}{6000\ L}\) × 30 L/min = 0.125 kg/min

Therefore, the rate of change of S is:

\(\frac{dS}{dt}\) = 0.6 - 0.125 = 0.475 kg/min

We can solve this differential equation to find the amount of salt in the tank as a function of time. The general solution is:

S(t) = \(S_{0}\) + 0.475 t

where \(S_{0}\) is the initial amount of salt in the tank. We can find \(S_{0}\) by using the initial conditions:

S(0) = 25 kg

Therefore, \(S_{0}\) = 25 kg.

So the amount of salt in the tank after t minutes is:

S(t) = 25 + 0.475 t, in kg.

If 5800 J of work is done when a person pushes a refrigerator weighing 720 N across a floor where the force of friction between the refrigerator and the floor is 480 N,  the refrigerator is going to move approximately 24.17 meters across the floor.

To determine the distance the refrigerator will move, we can use the work-energy principle. According to this principle, the work done on an object is equal to the change in its kinetic energy.

The work done on the refrigerator is given as 5800 J, and we know that work done is equal to the force applied multiplied by the distance moved in the direction of the force:

Work = Force × Distance

In this case, the force applied is the net force acting on the refrigerator, which is the difference between the force of pushing and the force of friction:

Net Force = Force of pushing – Force of friction

Substituting the given values, we have:

Net Force = 720 N – 480 N

Net Force = 240

Now, we can rearrange the work equation to solve for the distance:

Distance = Work / Net Force

Distance = 5800 J / 240 N

Distance ≈ 24.17 meters

Therefore, the refrigerator is going to move approximately 24.17 meters across the floor. The unit for distance is meters, which matches the SI unit for measuring length.

Mechanical equilibrium refers to a state in which a body is not experiencing any acceleration, meaning it is either at rest or moving at a constant velocity.

In order to achieve this state, the sum of the external forces acting on the body must be equal to zero. This means that all the forces acting on the body must be balanced and cancel each other out, resulting in no net force.

Additionally, the sum of the external torques acting on the body must also be equal to zero. Torque is a measure of rotational force and determines how much an object will rotate when subjected to a force.

Therefore, for a body to be in mechanical equilibrium, the forces acting on it must not only balance out, but the torques acting on it must also be balanced.

It's important to note that even if a body is being moved by a constant force, it can still be in mechanical equilibrium if the sum of the external forces acting on it is zero. This is because the constant force is countered by an equal and opposite force, resulting in a net force of zero.

Overall, mechanical equilibrium is a crucial concept in physics that helps us understand how objects behave when subjected to external forces.

Sergio put a force of 1.2 newtons on the object to perform 30 joules of work by pushing it 25

What is force?

Force is a physical quantity that describes the interaction between two objects, causing a change in their motion. It is measured in units of newtons (N) and is defined as the product of an object's mass and acceleration, as described by Newton's second law of motion.

The force exerted by Sergio on the object can be calculated using the formula:

Work = Force × Distance × cos(theta)

where Work is the work done (in joules), Force is the force applied (in newtons), Distance is the distance moved (in meters), and cos(theta) is the cosine of the angle between the force and the direction of motion (assuming the force is applied parallel to the direction of motion, cos(theta) = 1).

Rearranging the formula, we get:

Force = Work / (Distance × cos(theta))

Substituting the given values, we get:

Force = 30 J / (25 m × cos(0°))

Since cos(0°) = 1, we can simplify the expression to:

Force = 30 J / 25 m

Force = 1.2 N
