= mass of the car = 900 kg
= Initial speed of the car = 20 m/s
= Final speed of the car = 0 m/s
= Work done by the brakes on the car
Magnitude of work done on the car by the brakes is same as the change in kinetic energy of the car.hence
= time taken by the car to come to stop = 5 s
= Average power produced by the car
