A constant horizontal force F acting on the lower block produces an acceleration F/(2m+m) in the system, the two blocks always move together. (a) Find the coefficient of kinetic friction between the bigger block

A block of mass m is kept over another block of mass M and the system rests on a horizontal surface. A constant horizontal force F acting on the lower block produces an acceleration F/(2m+m) in the system, the two blocks always move together. (a) Find the coefficient of kinetic friction between the bigger block

An inclined plane is moving up with constant velocity v. A block kept on incline is at rest. Calculate the work done by gravity friction force
