As shown in Figure 3(a), a wooden block B with mass mB = 2.4 kg on a rough inclined plane is connected to a massless spring ( k = 160 N/m ) by a massless cord passing over a pulley P of radius R = 0.25 m and mass Mp = 0.60 kg. The angle of the inclined plane is θ = 37∘ and the coefficients of static and kinetic frictions are μs = 0.35 and μk = 0.30 respectively. The frictional force at the axle of the pulley is negligible. The pulley can be regarded as a solid disk. (a) The system is at rest and in this case, block B is on the verge of sliding down. Figure 3(a) i. Indicate (with labeled arrows) the forces acting on the pulley and the block. ii. Calculate the tension in the string and the extension of the spring. (You can assume that the tensions in the cord on either side of the pulley P are the same for this part.) (b) As shown in Figure 3(b), another wooden block A of mass mA = 1.2 kg made of the same material as block B is released from rest. It slides down a distance l down the rough inclined plane and collides with block B. The two blocks stick together and move down the incline with a common velocity v = 0.80 m/s immediately after collision and the pulley rotates. The cord does not stretch and does not slip on the pulley. Figure 3(b) i. Determine the distance l. ii. Determine the acceleration of the two blocks at the moment they move down together and the pulley starts to rotate. iii. Determine how much further down the slope the two blocks move together after they collide before the two blocks come to a momentary rest.

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.
