15. A 5.0 kg chunk of ice is sliding at on the floor of an ice-covered valley when it collides with and sticks to another 8.0 kg chunk
of ice that is initially at rest. Since the valley is icy, there is no friction. After the collision, how high above the valley floor
will the combined chunks go?
8kg
5kg 12m/s
