A ball is given a velocity `v` and angular velocity such that the ball rolls purely on a plank whose upper surface is rough enough to prevent slipping but lower surface contact with the ground is smooth. No other force is acting on system.

A cylinder executes pure rolling without slipping with a constant velocity on a plank, whose upper surface is rough enough, but lower surface is smooth. The plank is kept at rest on a smooth horizontal surface by the application of an external force F . The value of F is ?

A cylinder executes pure rolling without slipping with a constant velocity on a plank, whose upper surface is rough enough, but lower surface is smooth. The plank is kept at rest on a smooth horizontal surface by the application of an external force F . Choose the correct alternative:

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 rest on the ground. Initially P is fixed on the ground by a pin N . If N is suddenly removed

Why does a ball roll for a long time on a smooth surface than on a rough surface?

A solid sphere with a velocity (of centre of mass) v and angular velocity omega is gently placed on a rough horizontal surface. The frictional force on the sphere :

In the figure the plank resting on two cylinders is horizontal. The plank is pulled to the right such that the centre of smaller cylinder moves with a constant velocity v . Friction is large enough to prevent slipping at all surfaces. Find- (a) The velocity of the centre of larger cylinder. (b) The ratio of accelerations of the points of contact of the two cylinders with the plank.

During rolling without slipping, what is the velocity of the point in contact with the surface.

During rolling without slipping, what is the velocity of the point in contact with the surface.
