A spherical ball of mass M and radius R is projected along a rough horizontal surface so that initially(t=0) it slides with a linear speed v_(o), but does not rotate. As it slides, it begins to spin and eventually rolls without slipping. How long does it take to begin rolling without slipping?

1.	A spherical ball of mass M and radius R is projected along a rough horizontal surface so that initially(t=0) it slides with a linear speed v_(o), but does not rotate. As it slides, it begins to spin and eventually rolls without slipping. How long does it take to begin rolling without slipping?
Answer» SOLUTION :`t_(o)=(2V_(0))/(7mu_(K)G)`
