Solve the all parts of following question:
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 0.008 kg, and its velocity is +706 m/s. Her mass (including the gun) is 60 kg.
Part 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?
m/s
Part 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 +706 m/s?
m/s
Please show how you obtained the answer for above question.
