The car is moving at approximately 12.5 meters per second.

The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * \(v^2\)

where

KE = kinetic energy,

m =Mass of the object, and

v = velocity.

In this case, we are given the mass (m) of the car as 1600 kg and the kinetic energy (KE) as 125,000 J. To find the velocity .

Substituting the  values , we have:

125,000 J = 1/2 * 1600 kg *\(v^2\)

Now, we can solve for v by rearranging the equation:

\(v^2\) = (2 * 125,000 J) / 1600 kg

\(v^2\) = 156.25 \(m^2/s^2\)

Hi there!

We can begin by deriving the equation for how long the ball takes to reach the bottom of the cliff.

\(\large\boxed{\Delta d = v_it+ \frac{1}{2}at^2}}\)

There is NO initial vertical velocity, so:

\(\large\boxed{\Delta d= \frac{1}{2}at^2}}\)

Rearrange to solve for time:

\(2\Delta d = at^2\\\\t = \sqrt{\frac{2\Delta d}{g}}\)

Plug in the given height and acceleration due to gravity (g ≈ 9.8 m/s²)

\(t = \sqrt{\frac{2(60)}{(9.8)}} = 3.5 s\)

Now, use the following for finding the HORIZONTAL distance using its horizontal velocity:

\(\large\boxed{d_x = vt}\\\\d_x = 10(3.5) = \karge\boxed{35 m}\)

There would be 1 marker that measures 5 inches but less than 6.75 inches.

A "marker" refers to a writing instrument commonly used for making marks or writing on surfaces such as paper, whiteboards, or blackboards. Markers typically consist of a tube or barrel filled with ink or a similar liquid, which is dispensed through a tip or nib when applied to a surface. Markers are available in various colors and are commonly used in art, office work, education, and other activities where writing or drawing is involved.

To determine the number of markers that measure 5 inches but less than 6.75 inches, we need to find the range of marker lengths that fall within this interval.

The range between 5 inches (inclusive) and 6.75 inches (exclusive) can be calculated by subtracting 5 from 6.75, which gives us 1.75 inches.

If we assume that the marker lengths can have decimal values, we can round down 1.75 to the nearest whole number to get the number of markers within this range.

Therefore, there would be 1 marker that measures 5 inches but less than 6.75 inches.

The cannon will completely stop when it collides with the barrier.

To calculate the speed at which the cannon collides with the barrier, we can follow these step-by-step calculations:

Determine the initial momentum of the system.

Since the cannon is initially stationary, the initial momentum is zero.

Apply the conservation of linear momentum.

According to the principle of conservation of linear momentum, the initial momentum of the system (zero) is equal to the final momentum of the system. The final momentum is the momentum of the cannon after firing.

Calculate the final momentum of the system.

Let's assume the mass of the cannon is represented by 'm' and the final velocity of the cannon is represented by 'v'. The final momentum of the system is given by: final momentum = m × v.

Set up the equation.

Since the initial momentum is zero, we have: 0 = m × v.

Solve for the final velocity of the cannon.

Dividing both sides of the equation by 'm', we get: v = 0.

Interpret the result.

The calculation shows that the final velocity of the cannon is zero. This means that the cannon comes to a complete stop when it collides with the barrier.

The magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹ (Option E).

The electric flux through a surface is given by the product of the electric field strength and the area of the surface projected perpendicular to the electric field.

In this case, the electric field strength is 18 N C⁻¹, and the area of the sheet projected perpendicular to the electric field is 0.450 m²

(since the normal to the sheet makes an angle of 60° with the electric field). Multiplying these values gives the electric flux:

Electric flux = Electric field strength × Area

Electric flux = 18 N C⁻¹ × 0.450 m²

Electric flux = 8.1 N m² C⁻¹

In summary, the magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹. This value is obtained by multiplying the given electric field strength by the projected area of the sheet perpendicular to the electric field.
