Two blocks, A and B (with mass 55 kg and 130 kg, respectively), are connected by a string, as shown in the figure below. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is μk = 0.30. Determine the change in the kinetic energy of block A as it moves from (C) to (D), a distance of 17 m up the incline (and block B drops downward a distance of 17 m) if the system starts from rest. J

Two blocks are connected by a massless string over a pulley, as shown at right. Block A has a mass of 20 kg, and Block B has mass m. The coefficient of static friction between Block A and the horizontal surface is μs = 0.30 and the coefficient of kinetic friction between Block A and the surface is μk = 0.20. The mass m of block B can be selected to be any value between 0 kg and 40 kg. The value of m is chosen, and the system is released from rest. This is repeated for many different values of m. 6) On the axes provided, graph the friction force Ff acting on block A vs. the mass m of block B. Note the value of important points on the graph such as discontinuities, maxima, and minima. Show your work.

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s ) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? rad/s
