In a one-dimensional collision between two particles, their relative velocity is `vecv_(1)` before the collision and `vecv_(2)` after the collision

A

`vecv_(1)=vecv_(2)` if the collision is elastic

B

`vecv_(1)=-vecv_(2)` if the collision is elastic

C

`|vecv_(2)|=|vecv_(1)|` in all cases

D

`vecv_(1)=-kvecv_(2)` in all cases, where `kge1`

Text Solution

Verified by Experts

The correct Answer is:
B, D
`vecv_(2)-vecv_(1)=e(vecu_(1)-vecu_(2))` for `1-D` collision.
