A train moving along a level track has a maximum speed of 50 m/s. Determine the maximum power of the train engine if the total resistance to motion is 30 kN.

Determine the power required for a car to be driven along a straight road at a constant speed of 25 m/s if the resistance to motion is constant at 960 N.
