Question

The lead female character in the movie Diamonds Are Forever is standing at the edge of an offshore oil rig. As she fires a gun, she is driven back over the edge and into the sea. Suppose the mass of a bullet is 0.018 kg and its velocity is +700 m/s. Her mass (including the gun) is 55 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 +700 m/s? PLEASE WRITE ORIGIONAL FORMULAS AND SHOW HOW TO BREAK IT DOWN SO I CAN UNDERSTAND> Thanks!
