Question

A plank of mss M is placed on a rough horizontal surface and a constant horizontal force is applied to it. A man of mass m runs on the plank. Find the acceleration of the man so that the plank does not move on the surface. Coefficient of friction between the plank and the surface is µ . Assume sufficient friction between man and the plank to avoid slipping of man on the plank.

Answer 1

Answer:

find the acceleration of the man so that the plank does not move on the surface . coefficient of friction between the plank and the surface is u assume dufficient friction between man and the plank to avoid sliping of man on the plank.

Answer 2
