A 4.80 kg chunk of ice is sliding at 11.5 m/s on the floor of an ice-covered valley when it collides with and sticks to another 4.80 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?

In the figure, a 4.3 kg block is accelerated from rest by a compressed spring of spring constant 620 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction μk = 0.284. The frictional force stops the block in distance D = 7.4 m. What are (a) the increase in the thermal energy of the block–floor system, (b) the maximum kinetic energy of the block, and...
