A clay block of mass m moving to the right with speed v0 strikes a second block of mass 3 m moving to the left with the speed v0/3. The two clay blocks stick together after the collision. There are no outside forces acting on the blocks. How much kinetic energy was lost in this inelastic collision?

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.

Two pieces of clay, with masses m1 = 0.5 kg and m2 = 0.7 kg are moving as shown above, both with the same speed of 5.2 m/s. The angle is given by θ = 33∘. The two pieces collide and stick together. What is the speed of the combined 1.2 kg lump of clay after collision? How much kinetic energy was lost in the collision?

Starting from rest, a small block of mass m = 0.25 kg slides down an incline from a height h = 1.2 m. As it slides down, the block experiences a force of kinetic friction of constant magnitude fk = 2.1 N only over a distance L = 0.2 m, as shown in the figure. The incline is frictionless everywhere else. After reaching the bottom of the incline, the block strikes a larger block of mass M = 1.8 kg that is attached to a spring of spring constant k = 6.5 N/m. The large block was originally at rest. The blocks stick together upon impact and travel together on the frictionless horizontal surface. Assume that both blocks are subject to the regular force of gravity (g = 9.80665 m/s2). (a) Determine the speed of the small block right before it collides with the larger block. Answer: m/s (b) Determine the speed of the combination of the two blocks immediately after the collision. Answer: m/s (c) Determine the compression of the spring when the combination of the two blocks comes to rest. Answer: m
