What is the maximum speed at which a car can travel along a level road when its engine is developing 24kW and there is a resistance to motion of 800N?

    since power is given by F (force) times V and the force applied is 800 (to equate the resistance) we have 800 * v = 24 * 1000 v = 24 * 1000 / 800 v = 30 m/s

    maximum speed hence no more acceleration
