Question

what is the total momentum of the system before collision?

Answer 1

before total collision for two bodies , momentum m1u1+m2u2

Answer 2

The total momentum of the system before the collision is the same as the total momentum of the system after the collision.

The law of conservation of momentum is as follows:

• The total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision in an isolated system. In other words, the momentum obtained by item 2 equals the momentum lost by object 1.
