A block of mass m = 4.0 kg is released from rest at the top of an incline plane that makes an angle of 25∘ with the horizontal. It slides down a distance d = 7.0 m along the incline. What is the Angular Momentum of the block with respect to point X shown below. Approximate the block as a point mass. Assume negligible friction tetween the block and the incline. Magnitude of acceleration due to gravity is 10.0 m/s2. Select the closest answer.

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.

A block of mass m = 2.37 kg is attached to a spring with spring constant k = 835 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 28.3∘ with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.15. In the initial position, where the spring is compressed by a distance of d = 0.106 m, the mass is at its lowest position and the spring is compressed the maximum amount. Take the initial gravitational potential energy of the block as zero.
