In the figure shown, the plank is being pulled to the right with a constant speed v . If the cylinder does not slip then: .

A plank of mass M is placed on a smooth surface over which a cylinder of mass m and radius R is placed as shown in figure-5.63. Now the plank is pulled towards right with an external force F. If cylinder does not slip over the surface of plank find the linear acceleration of plank and cylinder and the angular acceleration of the cylinder.

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.

A uniform plank of mass m, free to move in the horizontal direction only , is placed at the top of a solid cylinder of mass 2 m and radius R. The plank is attached to a fixed wall by mean of a light spring constant k. There is no slipping between the cylinder and the planck , and between the cylinder and the ground. Find the time period of small oscillation of the system.

A plank of mass M , is placed on a smooth surface over which a cylinder of mas m(=M) annd radius R=1m is placed as shown in figure. Now the plane is pulled towards the right wilth an external force F(=2Mg) . If the cyinder does not slip over the surfcace of the plank, find the linear acceleration of he plank and the cylinder and the angular acceleration of the cylinder. (Take g=10 ms^(2) )

A uniform solid cylinder of mass m rests on two horizontal planks. A thread is wound on the cylinder. The hanging end of the thread is pulled vertically down with a constant force F(figure). Find the maximum magnitude of the force F which still does not bring about any sliding of the cylinder, if the coefficient of friction between the cylinder and the planks is equal to k. What is the acceleration w_(max) of the axis of the cylinder rolling down the inclined plane?

A uniform plank of mass m = 1kg , free to move in the horizontal direction only, is placed at the top of a solid cylinder of mass 2m and radius R . The plank is attched to a fixed wall by means of light spring of spring constant k = 7N//m^(2) . There is no slipping between the cylinder and the plank, and between the cylinder and the ground. the angular frequency of small oscillations of the system is
