51 kg. (a) What recoil velocity does she acquire in response to a single
shot from a stationary position, assuming that no external force keeps
her in place? (b) Under the same assumption, what would be her recoil
velocity if, instead, she shoots a blank cartridge that ejects a mass of
5.0 X 10-4 kg at a velocity of +720 m/s?
