Q2. A block of massmrests on the left edge of a block of larger massM. The coefficient of kinetic

friction between the two blocks is , and the surface on which the larger block rests is frictionless.

A constant horizontal force of magnitude F is applied to the block of mass m, setting it in motion

as shown in figure below.

(a) Draw a free body diagram indicating all the forces acting on mass m.

(b) What is the acceleration of the mass m?

(c) Draw a free body diagram indicating all the forces acting on mass M.

(d) What is the acceleration of mass M?

(e) How long will it take the block of mass m to cover a distance L on the larger block?

(f) How far does the larger block moves during the time calculated in part (a)?
