A BB gun is fired at a cardboard box m2 = 1.85 kg on a frictionless surface. The BB has a mass of m1 = 0.044 kg and travels at a velocity of v1 = 93 m/s. It is observed that the box is moving at a velocity of v2 = 0.93 m/s after the BB passes through it.
Part (a) Write an expression for the magnitude of the BB's velocity as it exits the box vf.
Part (b) What is the BB's velocity in m/s?
Part (c) If the BB doesn't exit the box what will the boxes velocity be in m/s?
