If m(1) collides another mass body m(2) ...

If `m_(1)` collides another mass body `m_(2)` at rest elastically, then what will be the fraction of kinetic energ lost by `m_(1)` to the second body?

Text Solution

Verified by Experts

The fraction of energy lost to `m_(2)=((m_(1)-m_(2))/(m_(1)+m_(2)))^(2)`
