A 0.001 kg bullet is fired from a gun and lodges inside a wooden block of mass 0.2 kg. The block and bullet then slide on a rough floor with a coefficient of kinetic friction μk = 0.4 before coming to rest after sliding a distance of 3 m. Compare KEi, the initial kinetic energy of the bullet, with Wf, the work done by the frictional force between the block and the floor in stopping the block. KEi > Wf KEi = Wf KEi < Wf

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.

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.

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?
