Questions
A solid sphere of mass M and radius r slips on a rough horizontal plane. At some instant it has translational velocity v0 and rotational velocity about the centre v0/2r . The translational velocity after the sphere starts pure rolling
detailed solution
Correct option is A
Angular momentum can be conserved about lowest point.mv0r+25mr2v02r=mv'r+25mr2v'r⇒10mv0r+2Mv0r10=7mv'r5⇒v'=6v07Talk to our academic expert!
