Question

"blocks A and B are moving toward each other along the xaxis. Block A has a mass of 2.0 kg and a velocity of 50 m/s(in the positive X direction) , while B has a mass of 4.0 kg and avelocity of -25m/s (in the negative direction). They sufferan elastic collision and move off along the x axis. after thecollision the velocities of A and B respectively are: " Thank you!

Explanation / Answer

Given m = 2 kg

           u=50 m / s

          M = 4kg

          U = -25 m/ s

For elastic collsion coefficient of restitution e =1

    ( V – v ) / ( u – U ) = 1

         V – v = u– U

                  = 75
