In the following figure, a sphere of radius 3m rolls on a plank. The accelerations of the sphere and the plank. The accelerations of the sphere and the plank are indicated. The value of alpha is

A sphere of radius 1 m is kept on a plank kept on horizontal surface. Accelerations of plank and centre of sphere are indicated in the figure. If sphere is not slipping on the plank then its angular acceleration is

A plank of mass M is placed on a rough horizontal force F is applied on it A man of mass m rens on the plank find the acceleration of the man so that the plank does not move on the surface . The coefficent of friction between the plank and the surface is mu Assume that the man does not slip on the plank

A plank of mass m_(1) with a uniform solid sphere of mass m_(2) placed on it rests and a force F is applied to the plank. The acceleration of the plank provided there is no sliding between the plank and the sphere is (F/(m_(1)+n/7m_(2))) then the value of n is

Block A of mass m rests on the plank B of mass 3m which is free to slide on a frictionless horizo-ntal surface. The coefficient of friction between the block and plank is 0.2. If a horizontal force of magnitude 2 mg is applied to the plank B, the acceleration of A relative to the plank and relative to the ground respectively, are:
