Detailed Solution

Kinetic energy of a body of mass m1.K1 = 12m1v12 = p222m2Again, kinetic energy of a body of mass m2.K2 = 12m2v22 = p222m2if p1 = p2, K1K2 = m2m1If m2> m1Then, K1 > K2 i.e. the kinetic energy of light body will be more than the kinetic energy of heavy body when both have same momentum.
