A plank of mass M is placed on a rough horizontal surface. A man m walks on the plank with an acceleration 'a' while the plank is also acted upon by a horizontal force F whose magnitude and direction can be adjusted to keep the plank at rest.

The coefficient of friction between plank and surface is `mu`. Choose the correct options.

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 man is running with a constant acceleration on a plank which is placed on a horizontal smooth surface. Then choose the correct option(s):

A man is running with a constant acceleration on a plank which is placed on a horizontal smooth surface. Then choose the correct option(s):

A plank of mass M is placed on a rough horizontal surface and a contant horizontal force F is applied on it . A man of mass m runs on the plank find the range of acceleration of the man that the plank does not move on the surface is mu .Assume that the does not slip on the plank

A block of mass m is placed in equilibrium on a moving plank. The maximum horizontal acceleration of the plank for mu=0.2 is:

A plank of mass M rests on a smooth horizontal plane. A sphere of mass m and radius r is placed on the rough upper surface of the plank and the plank is suddenly given a velocity v in the direction of its length. Find the time after which the sphere begins pure rolling, if the coefficient of friction between the plank and the sphere is mu and the plank is sufficiently long.

A block of mass m is on the smooth horizontal surface of a plank of mass M The plank is on smooth horizontal surface Now, a constant horizontal force F acts on M. Now, for a person standing on the ground:

A man of mass m is standing on a plank of equal mass m resting on a smooth horizontal surface. The man starts moving on the plank with speed u relative to the plank. The speed of the man relative to the ground is
