A particle of mass 2 kg starts moving in a straight line with an initial velocity of at a constant acceleration of . Then rate of change of kinetic energy

A car of mass 1000 kg moves at a constant speed of up an incline. Assume that the frictional force is 200 N and that where, is the angel of the incline to the horizontal. The . Find the power developed by the engine

The work done in dragging a stone of mass 100 kg up an inclined plane 1 in 100 through a distance of 10 m is (take )

Statement ITwo particles moving in the same direction do not lose all their energy in a completely inelastic collision.
Statement IIPrinciple of conservation of momentum holds true for all kinds of collisions.

If momentum is increased by 20%, then kinetic energy increases by
