Question:

A 1110 kg car traveling on a flat road at 72 km/h arrives at that speed at an inclined area 10 where it begins to descend. To control the car, the driver

Apply the brakes to reduce the kinetic energy by 51 [kJ].

a) What is the final speed of the car?

b) In the braking process, what is the work done by the weight and friction?

c) The more kinetic energy must be removed by the brakes to stop the

car?
