1.Block X of mass M slides across a horizontal surface where friction is negligible. Block X collides with blockY of mass 2M that is initially at rest, as shown in Figure 1. After the collision, both blocks slide together with a speed vs , as shown in Figure 2.: 9/2Mv^2 1. Whatisthe speed ofthe center of mass ofthe two-block system immediately before the collision?: The speed is v. 2. How could a student verify that the collision under consideration is an inelastic collision for the two-bl...
