Question

a light body and a heavy body have same momentum .which one has greater kinetic energy? support your answer with an explanation.

Answer 1

Since both have same momentum the lighter one has high velocity according to the equation p=mv,
Therefore lighter body has higher kinetic energy because K=p²/2m

Answer 2

According to the question, a light body and a heavy body have same momentum.

Between this two bodies the light body will gain more kinetic energy than the heavy body.

Because, greater the mass is equals to greater the gravitational force which resists the the velocity as well as the kinetic energy.
