A bowling ball of mass mb = 4.3 kg is rolled down the lane with a velocity of v1 = 2.1 m/s. It strikes a single remaining pin mp = 0.85 kg head on. After the collision the bowling ball has a velocity (in the same direction) of v2 = 1.8 m/s. Part (a)  Write an expression for the velocity of pin in the horizontal direction after the impact, vp.  Part (b)  What is the pins speed in m/s?  Part (c)  Assuming the coefficient of friction is μk = 0.1, how far in meters could the pin slide before stopping if it doesn't topple?
