Two bodies one light and other heavy have equal momentum.Which of them has higher kinetic energy?
(Aajma Manoj asked)
Answer:
The lighter body will have greater kinetic energy.
Explanatiom
Momentum, p=mv
squaring both sides, p2 = m2v2
Kinetic Energy = 1/2 mv2 = p2/2m
Therefore, for bodies of equal momenta, kinetic energy is inversely proportional to mass.
