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.
