Question

Ball A collide with ball B which is at rest ,after the collision which of the following condition is possible (ball A comes to rest and Ball B start moving)(both balls move in same direction)(both balls move in opposite directions)(both balls are at rest )

Answer 1

Answer:

Both balls have same mass m

the linear momentum before collision is mu+0=mu

suppose after collision they have velocities V1and V2

then the momentum after collision will be mV1+mV2=m(V1+V2)

momentum should be conserved
