A 0.600-kg wood block is firmly attached to a very light horizontal spring k = 200 N/m as shown in the figure. It is noted that the block-spring system, when compressed 5.00 cm and released, stretches out 4.00 cm beyond the equilibrium position before stopping and turning back. What is the coefficient of kinetic friction between the block and the table?

Work. A block of mass m = 2.00 kg is attached to a spring of force constant k = 500 N/m as shown on the right. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. There is friction between the surface and the block. The coefficient of friction between block and surface is μk = 0.350. (a) (3 pts) What is the work done by the elastic force during the displacement? (b) (2 pts) What is the work done by the kinetic friction on the block during its motion? (2 pts) (d) (5 pts) What is the speed of the block as it passes through the equilibrium position? Use work-kinetic energy theorem.

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
