An engine accelerate a car of mass `800 kg` to a speod of `72 km//h`. If the frictional force is `10 N` per tonne, the power developed by the engine is:

The power engine which accelerates a car of mass 800 kg to a speed of 72 km/h from rest in 32s is

A car weighing 500 kg climbs up a hill of slope 1 in 49 with a velocity of 36 KMPH. If the frictional force is 50 N, the power delivered by the engine is

A train having 60 wawgons each weight 25 tonner moving with a speed of 72 km//h . If the force 10 N per tonne , the power development is:

A train weighing 100 metric ton is running on a level track with a uniform speed of 72km h^(-1) . If the frictional resistance amounts to 0.5kg per metric ton, find the power of the engine

An engine delivered power of 30 kW to a car of mass 1250 kg and velocity of 30 m/s . If the friction force of surface is 750N what will be the maximum acceleration of car ?

Engine of a car of mass 1500kg, keeps car moving with constant velocity 5ms^(-1) . If frictional force is 1000 N, power of engine is …………..

A train of mass 800 metric tons is moving with a velocity of 72 KMPH. If the resistive force acting on the train is 10N per metric ton, the power of the engine is
