Consider a bowling ball of mass, m=2kg, and radius, r=25cm. You can think of the bowling ball as a spherical shell.
First consider the situation where you impart a linear velocity of, v= 5m/s to the ball (no spin) and let it go on the floor. Approximately how long does it take for the ball to start to roll?
