A bowling ball of mass 7.2 kg and radius 10 cm rolls off the back of the Staten Island Ferry into New York Bay. Assuming no other forces than gravity and buoyancy, how long with it take to sink to the bottom 20 m below? How does this compare to how long it would take the bowling ball to fall to the ground from atop a 20 m building? Give me a factor. It is X times longer.
