Question

Two bodies of masses M1 and M2 are moving with velocities U1 and U2 along the same After the elastic collision, compare their velocities. What will happen if. (1) masses of the bodies are equal (ii) One of the body is at rest.​

Answer 1

Answer:

For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity. Hence, the velocities are interchanged i.e. the speeds are interchanged which in turn interchanges the momentum.
