A penny of mass 3.10 g rests on a small 20.0 g block supported by a spinning disk with radius of 12.0 cm. The coefficients of friction between block and disk are 0.850 (static) and 0.590 (kinetic) while those for the penny and block are 0.360 (kinetic) and 0.505 (static). What is the maximum rate of rotation in revolutions per minute that the disk can have, without the block or penny sliding on the disk? rev/min

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 61.7 kg block is suspended on an inclined surface at angle θ = 50.7∘ by a cable attached to a winch, as shown in the figure. The coefficients of friction between the block and inclined surface are: μs = 0.66, μk = 0.48 What is the maximum tension in the cord, T, such that the block does not slip? If the maximum tension, evaluated in the previous part, is marginally exceeded, what is the acceleration of the crate up the slope? Number Units

Consider the Atwood machine in Fig. 1, where two blocks, one resting on top of the other. The blocks are tied to an ideal pulley (massless) through the rope and the rope can slip through the pulley without friction. The coefficients of static and kinetic frictions between the blocks are μ, and there is no friction between the block and the ground. Someone pulled the pulley with a force F. a. What will the maximum acceleration of the system be if the top block does not slip? ( 3 points) b. Now, assume that slipping does occur between the blocks. Draw the free-body diagrams of two blocks and the pulley w. (4 points) c. Express the acceleration of each block in terms of F, m1, m2, μ, and g when there is slipping. (Hint: pulley is massless, so the sum of the tensions in the rope equals to F ) (3 points)
