A 14 lb bowling ball is thrown onto a lane with a backspin angular speed wo - 10 rad/s and forward velocity vo 17 mph. After a few seconds, the ball starts rolling without slip and moving forward with a speed v 17.2 ft/s. Let r=4.25 in. be the radius of the ball, and let KG 2.6 in. be its radius of gyration. Ge Mk m Determine the work done by friction on the ball from the initial time until the time that the ball starts rolling without slip. The work done by friction on the ball is ft-lb.
