A block of weight W = 200 N on an incline of 20∘ with respect to the horizontal direction is subjected to a constant force P that is inclined by an angle of 30∘ with respect to the horizontal direction, as shown in Figure 3. The coefficients of static and kinetic friction between the block and the incline are μs = 0.30 and μk = 0.20, respectively. a) Draw a free body diagram of the block and find the maximum force P = Pmax that can be applied before the block starts to slide up the incline. Find the normal force N exerted by the incline on the block when P = Pmax . b) For a force P = 500 N, draw a free body diagram of the block and find its (constant) acceleration a up the incline. c) If the block starts from rest at time t = 0 when the force P = 500 N is first applied to the block, find the speed v = v(t) of block and the distance s = s(t) it travels up the incline at any time t.

An initially stationary block of mass m = 5.0 kg is attached to a relaxed spring with a spring constant K = 16 N/m on a rough plane inclined at an angle θ (with cos⁡θ = 0.8 and sin⁡θ = 0.6). The coefficient of kinetic friction between the block and the plane is μk = 0.40. A vertically downward uniform force F = 240 N acts on the block as it moves from A to B a distance d = 2.5 m down the plane. During this descent from A to B , calculate the amount of work done on the block by: a) the normal force, b) the gravitational force, c) the spring force, d) the force F , and e ) the force of kinetic friction. f) Deduce the kinetic energy and the speed of m as it passes through point B.

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.
