Masses A and C are connected by a cord as shown below. The middle mass, B, is held motionless by some method which is not drawn. A force is applied to mass A so that A and C move at constant speed. (Remember that B is motionless.) If the coefficient of kinetic friction between all surfaces is μk = 0.35, what is the applied force F?

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

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a cord to a block with mass m2 = 0.850 kg as shown in the figure below. The cord 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 cord does not stretch and does not slip on the pulley, and that the mass of the cord 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
