A curved incline is used to give a box a certain velocity as it slides down. The box has a mass of m1=4.92 kg. Friction is negligable. The box starts from rest at h= 5.00 m above the flat surface at the bottom of the incline. After moving down, it collides with a second box m2=10.5kg, also initially at rest. Teh collision is elastic. Find the maximum height to which m1 rises after the collision
