A bowling ball of mass M and Radius R (treated as a solid sphere) is thrown along a level surface so that initially (t = 0) it slides with a linear speed Vo but dows not rotate. As it slides, it begins to spin, and eventually rolls without slipping. Assume the coefficient of kinetic friction is µk
a) How long does it take to begin rolling without slipping?
b) What is the change of kinetic energy in the whole process?
