Question 1. A block of ice mass m1 is sliding on an ice-covered valley when it collides with another block of ice with mass m2. Since the valley is icy, you may neglect friction. (a) How high above the valley floor will the two blocks go if they stick together after the collision? (b) How high will m2 go if m1 stops after the collision?
