A ball of mass m collides with a stationary identical ball a speed `v_(0)`. Find the impulse of the colliding balls `(e=1//2)`.

Text Solution

Verified by Experts

Impulse `= (m_(1)m_(2))/(m_(1)+m_(2))(1+e)(u_(1)-u_(2))`
Putting `m_(1)=m_(2)e=1//2, u_(1)=v_(0), u_(2)=0`, we obtain
Impulse `= 3//4 mv_(0)`.
