In case of pure rolling what will be velocity of point A of the ring of radius R ?

A man pulls a solid cylinder ( initially at rest ) horizontal by a massless string. The string is wrapped on the cylinder and the cylinder performs pure rolling. Mass of the cylinder is 100kg , radius is pi metre & tension in string is 100N . Then the angular speed of the cylinder after one revolution will be :

If v_2,v_2 , and v_3 are the velocities of points P,C and Q respectively lying on body doing pure rolling motion, then correct order of velocities will be

A very large plank P of some unknown mass is being moved with velocity v_(0)hati under application of an external force (not shown in figure). Simultaneously a block B of mass m placed on the plank is also moving with velocity v_(0)hatk . All these velocities are with respect to ground frame and at t=0 . Coefficient of frictioin between the plank and the block mu . Choose the correct option(s).

In the figure shown, a solid sphere of mass 'm' and radius r is released from a height 6r to slide down a smooth surface. A plank of same mass 'm' touches the horizontal portion of the surface at the ground. The co-efficient of friction between the plank and the sphere is mu and that between the plank and the ground is mu//4 . Find the work done by the friction force between the plank and the ground till the sphere starts pure rolling on the plank. Neglect the height of the plank.

A bullet of mass m moving with a velocity of u just grazes the top of a solid cylinder of mass M and radius R resting on a rough horizontal surface as shown and is embedded in the cylinder after impact. Assuming that the cylinder rolls without slipping, find the angular velocity of the cylinder and the final velocity of the bullet.

A system of identical cylinders and plates is shown in Fig. All the cylinders are identical and there is no slipping at any contact. The velocity of lower and upper plates are V and 2V , respectively, as shown in Fig. Then the ratio of angular speeds of the upper cylinders to lower cylinders is

Consider a cylinder rolling on a horizontal plane. Its linear velocity is v and rotational angular velocity is omega . Find its angular momentum about point P on the ground as shown in Fig. What happens to this angular momentum if the cylinder is rotating in opposite direction but moving translationally in the same direction.

A system is shown in fig. Assume that the cylinder remains in contact with the two wedge. Then the velocity of cylinder is
