A body of mass mmoves in a circular path with uniform angular velocity. The motion of the body has constant
A body of mass 10 kg is moving with a velocity 20 m s−1. If the mass of the body is doubled and its velocity is halved, find:(i) the initial kinetic energy, and (ii) the final kinetic energy.
A body of mass 5 kg is moving with a velocity of 10 m s-1. The ratio of its initial kinetic energy and final kinetic energy, if the mass of the body is doubled and its velocity is halved will be
