Blocks A and B, with masses mA = 5 kg and mB = 3 kg, respectively, are connected by a spring of stiffness k = 20 N/m and unstretched length L0 = 0.75 m. The blocks are at rest and separated by the distance L0 when block B is given a velocity to the right with magnitude V0 = 15 m/s. The friction between the blocks and the horizontal surface on which they rest is negligible.

Assuming that the spring can be squeezed so that d = 0, verify that the blocks A and B will collide with one another in the ensuing motion by computing the velocities of the blocks when d = 0.
