A 1000-kg car is accelerated from rest to 85 km/h in 10 s. Assuming that no mass is lost and the car accelerates on a flat, horizontal surface, what is the change of the total energy of the car? How much power is required to change this total energy? Would the total energy change and power required change if it were to accelerate in 5 s?
