A car of mass m is driven with acceleration 'a' along a staright level road against a constant external resistive force R' . When velocity of car is v , the rate at which the engine of car is doing work will be ...........

A car of mass 500 kg is driven with acceleration 1 m//s^(2) along straight level road against constant external resistance of 1000 N. When the velocity is 5 m//s the rate at which the engine is working is :

A car is moving along a straight level road with constant speed. Then

A vehicle of mass 1250 kg is driven with an acceleration 0.25 ms^(-2) along a straight level road against an external resistive force 500 N. Calculate the power delivered by the vehicle's engine if the velocity of the vehicle is 30 ms^(-1) .

A car is accelerated on a leveled road and attains a velocity 4 times of its initial velocity. In this process, the kinetic energy of the car

A car of mass m is accelerating on a level smooth road under the action of a single F. The power delivered to the car is constant and equal to P. If the velocity of the car at an instant is v, then after travelling how much distance it becomes double? .
