A 5.05 kg chunk of ice is sliding at 14.5 m/s on the floor of an ice-covered valley when it collides with and sticks to another 5.05 kg chunk of ice that is initially at rest. Since the valley is icy, there is no friction. After the collision, the blocks slide partially up a hillside and then slide back down. How fast are they moving when they reach the valley floor again?
