(a)
Conservation of energy:
P.E = K.E
v0 = 8.4 m/s
Conservation of momentum:
A package of mass m is released from rest at a warehouse loading dock and slides down a h = 3.6 m high frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m, from the bottom of the chute.
(a) Suppose the packages stick together. What is their common speed after the collision?
m/s
(b) Suppose the collision between the packages is elastic. To what height does the package of mass m rebound?
cm
