The light body

Vedclass · Answer

(A) The relationship between kinetic energy $(K)$,momentum $(p)$,and mass $(m)$ is given by the formula $K = \frac{p^2}{2m}$.Since the momentum $(p)$ is the same for both bodies,the kinetic energy is inversely proportional to the mass $(K \propto \frac{1}{m})$.Therefore,the body with the smaller mass (the lighter body) will have a larger denominator,resulting in a greater value for kinetic energy.Thus,the lighter body has more kinetic energy than the heavier body.

$A$ light and a heavy body have the same momentum. Which one will have greater kinetic energy?
