Question

A bowling ball of mass M and radius R (treated as a uniform solid sphere) is thrown along a level floor with initial kinetic energy K0. It is thrown so that initially (at t = 0) it has a linear speed ?0 but does not rotate. As the ball starts sliding, kinetic friction slows down translational motion from ?0 to v = vcom, while at the same time providing torque with respect to the center of mass of the ball; this torque speeds up the rotational motion with angular speed changing from 0 to ?. That process stops when the ball
