A solid cylinder rolls without slipping along a horizontal plane with velocity 66 ~m / s and reaches a plane inclined at 60^ with the horizontal. If there is sufficient friction to prevent slipping then the body starts rolling up the inclined plane with the velocity v. Find the value of v(i n m / s) .

Correct answer

44

Step-by-step solution

Initial angular momentum of the solid sphere about B = I + m v_ cm r MR ^2 2 v _ C R + mv _ C R Final angular momentum of the solid sphere at B=m v^2 R+ M R^2 2 v^ R Angular momentum about the B will remain conservation L_i=L_F Angular momentum about the B will remain conservation
