1. A 63.0 kg astronaut is on a spacewalk when the tether line to the shuttle
breaks. The astronaut is able to throw a spare 10.0 kg oxygen tank in a
direction away from the shuttle with a speed of 12.0 m/s, propelling the
astronaut back to the shuttle. Assuming that the astronaut starts from rest
with respect to the shuttle, find the astronaut's final speed with respect to
the shuttle after the tank is thrown.
2. An 85.0 kg fisherman jumps from a dock into a 135.0 kg rowboat at rest
on the west side of the dock. If the velocity of the fisherman is 4.30 m/s
to the west as he leaves the dock, what is the final velocity of the fisher-
man and the boat?
3. Each croquet ball in a set has a mass of 0.50 kg. The green ball, traveling
at 12.0 m/s, strikes the blue ball, which is at rest. Assuming that the balls
slide on a frictionless surface and all collisions are head-on, find the final
speed of the blue ball in each of the following situations:
