Question

A light body and a heavy body have the same momentum which of the two bodies will have greater kinetic energy?

Answer 1

As kinetic energy K=P*2/2m

That means K is inversely proportional to m(mass)

Therefore lighter body will have greater kinetic energy

Answer 2

Answer:  we know,

kinetic energy = p/2m where p is momentum and m is mass

or kinetic energy ∝ 1/mass

momentum of both body is sam

so kinetic enrgy of lighter body will be more.
