Question
A sphere S rolls without slipping, moving with a constant speed on a plank P. The friction between the upper surface of P and the sphere is sufficient to prevent slipping, while the lower surface of P is smooth and rests on the ground. Initially, P is fixed to the ground by a pin T. If T is suddenly removed-
Options
A.S will begin to slip on P
B.P will begin to move backwards.
C.the speed of S will decrease and its angular velocity will increase.
D.there will be no change in the motion of S and P will still be at rest.
