Question

Two balls of identical masses are moving with equal velocities in the opposite direction. Find their momentum after collision. If mass of one object was doubled,how would the momentum change​

Answer 1

Answer:

When the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero. For linear momentum to be conserved after the collision, both balls must rebound with the same velocity.

Hence, the resultant velocity is zero
