In Fig a sphere of radius 2 m rolls on a plank. The accelerations of the sphere and the plank are indicated. The value of alpha is

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

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 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 solid sphere of mass m and radius R is placed over a plank of same mass m . There is sufficient friction between sphere and plank to prevent slipping. Acceleration of centre of mass of sphere is
