Explanation:
<u>Frictional Force
</u>
When the car is moving along the curve, it receives a force that tries to take it from the road. It's called centripetal force and the formula to compute it is:

The centripetal acceleration a_c is computed as

Where v is the tangent speed of the car and r is the radius of curvature. Replacing the formula into the first one

For the car to keep on the track, the friction must have the exact same value of the centripetal force and balance the forces. The friction force is computed as

The normal force N is equal to the weight of the car, thus

Equating both forces

Simplifying

Substituting the values


<h3>Answer;</h3>
<em>Energy is transferred.</em>
<h3>Explanation;</h3>
- Work is the force applied over a given distance, in other words work is the product of force and distance. That is; Work = force × distance.
- Work is measured in Joules.
- Energy on the other hand, is the ability to do work.
- According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.
