Elastic Collisions
11. Momentum & Impulse / Elastic Collisions / Problem 1

In an experiment, a block of mass 2m is released from rest down the 4.2 m high curve, as shown. The block collides with a second block of mass 3m at the bottom of the curve. Assuming a perfectly elastic collision, determine the rebound height of the 2m block.
