A cylindrical drum, pushed along by a board rolls forward on the ground. There is no slipping at any contact. The distance moved by the man who is pushing the board, when axis of the cylinder covers a distance `L` will be.

A bobbin is pushed along on a rough stationary horizontal surface as shown in the figure. The board is kept horizontal and there is no slipping at any contact points. The distance movedby the board when distance moved by the axis of the bobbin is l is .

A man pushes a cylindrical drum through a board of length l as shownin figure-5.109. The drum rolls forward on the ground a distance of (1)/(2) There is no slipping at any instant.During the process of pushing the board the distance moved by the man on the ground is :

A man pushes a cylinder of mass m_1 with the help of a plank of mass m_2 as shown in figure. There in no slipping at any contact. The horizontal component of the force applied by the man is F. (a) the acceleration fo the plank and the center of mass of the cylinder, and (b) the magnitudes and direction of frictional force at contact points.

A boy pushes a cylinder of mass M with the help of a plank of mass m as shown in figure. There is no slipping at any contact. The horizontal component of the force applied by the boy on the plank is F. Find (a) The acceleration of the centre of the cylinder (b) The friction force between the plank and the cylinder

A cylidrical drum is pushed by a wooden plank as shown in the fig.The cylinder rolls forward on the ground by a distance l/2 equal to half of the length of the plant.there is no slipping at any point of contact. Where is the board then? .
