Question

20) Explain the law of conservation of momentum in collision of two balls.

Please help!​

Answer 1

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Answer 2

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision..

For this problem, note that v2=0 and use conservation of momentum. Thus, p1 = p′1 + p′2 or m1v1=m1v′1+m2v′2. v'2=m1m2(v1−v'1) v ′ 2 = m 1 m 2 ( v 1 − v ′ 1 ) .
