USE conservation of momentum for-
mula. The astronaut will have the same mo-
mentum as the oxygen tank - only in the
reverse direction. ——
A 62.5 kg astronaut is on a space walk when
the tether line to the shuttle breaks. The
astronaut is able to throw a 11.0 kg oxygen
tank in a direction away from the shuttle with
a speed of 11.4 m/s, propelling the astronaut
back to the shuttle.
Assuming that the astronaut starts from
rest, find the final speed of the astronaut after
throwing the tank.

The equation for theconservation of momentum: 62.5 kg * (-v) + 11.0 kg * 11.4 m/s = 0; v = 11.0 kg * 11.4 m/s / 62.5 kg = 2.006 m/s
