Chapter 10, Problem 79P(choose chapter or problem)
Combining Conservation Laws.? A 5.00-kg chunk of ice is sliding at 12.0 m/s on the floor of an ice-covered valley when it collides with and sticks to another 5.00-kg chunk of ice that is initially at rest (?Fig. P8.73?). Since the valley is icy, there is no friction. After the collision, how high above the valley floor will the combined chunks go?
