A package of mass m is released from rest at a warehouse loading dock and slides down a 3.0-m-highfrictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2 m, from the bottom of the chute. Suppose the packages stick together. What is their common speed after the collision? Suppose the collision between the packages is elastic. To what height does the package of mass m rebound?
