Two bodies of mass 4 g and 25 g are moving with equal kinetic energies. The ratio of magnitude of their linear momentum is :

Step-by-step solution

The kinetic energy K of an object is given by K = 1 2 m v 2 = p 2 2 m . . . 1 Following equation (1), for the two given bodies, it can be written that p 1 2 2 m 1 = p 2 2 2 m 2 ⇒ p 1 p 2 = m 1 m 2 = 4 25 = 2 5
