A light cord is passed around a frictionless pulley and connected to the two masses as shown, with m2 pulled by a constant horizontal force, F. The coefficient of kinetic friction between m1 and m2 is the same as that between m2 and the horizontal surface. Find an expression for μk (in terms on F, m1, m2 and any constants needed) if the blocks are to move with constant speed.

Block 1 of mass 2 m is connected to Block 2 of mass m using an inextensible rope and pulley of negligible mass as shown in the diagram below. The coefficient of kinetic friction between Block 1 and the inclined plane is μ1 whereas that between Block 2 and the inclined plane is μ2. It is observed that Block 1 accelerates down the incline pulling Block 2 up the incline. (a) Derive an expression for the acceleration of the system, a in terms of the given variables only m, μ1, μ2 and any constants, such as g. (b) Calculate the tension in the string given m = 3.0 kg, θ1 = 60∘, θ2 = 30∘, μ1 = 0.2, μ2 = 0.4 (c) If the inclined planes are frictionless, what is the acceleration of the system? Hint: Modify the expression you derived in part (a) to obtain an expression for the acceleration of the system in this case.

Two blocks are connected by a negligible mass string passing over a frictionless pulley of radius R = 0.1 m and moment of inertia I = 0.02 kgm2. A 64.8 N horizontal force acts on the 8.00−kg object. The 8 kg block moves to the right with a constant linear acceleration a. The coefficient of kinetic friction between the horizontal surface and the 8 kg block μk is 0.5. Determine (a) the linear acceleration a of the system, (b) T1 and T2 the tensions in the two parts of the string.
