A light and a heavy object have the same momentum. Find out the ratio of their kinetic energies. Which one has a larger kinetic energy?

Question

Philoid · Accepted Answer

Momentum = mv

Since both have same momentum, hence

P = p’

Mv = m’v’

If M > m

Then v < v’

Since, v

hence KE < KE’

Thus, the light object has higher kinetic energy.
