Find the kinetic energy of a body of mass 1 kg moving with a uniform velocity of 10 m s−1.
Kinetic energy =12mv2=12×1×102=50 J
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
Calculate the kinetic energy of a body of mass 2 kg moving with a speed of 10ms−1.
