A block of mass 3.3 kg is attached to a string that passes over a pulley. The block is initially held at rest, and then pulled by a force F = 84 N to the right, as shown in the figure. The pulley is like a disk of mass 0.6 kg and radius 0.8 cm, and is frictionless. What will be the kinetic energy of the block when it has moved up a distance 2.2 m?

A block of mass m1 = 16.0 kg is connected to a block of mass m2 = 32.0 kg by a massless string that passes over a light, frictionless pulley. The 32.0−kg block is connected to a spring that has negligible mass and a force constant of k = 300 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 16.0−kg block is pulled a distance h = 18.0 cm down the incline of angle θ = 40.0∘ and released from rest. Find the speed of each block when the spring is again unstretched. vm1 = m/s vm2 = m/s

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

4.2 A block of mass m is connected by a string of negligible mass to a spring with spring constant K which is in turn fixed to a wall. The spring is horizontal and the string is hung over a pulley such that the mass hangs vertically. The pulley is a solid disk of mass M and radius R. As shown in the diagram below, the spring is initially in its equilibrium position and the system is not moving. a) Use energy methods, to determine the speed v of the block after it has fallen a distance h. Express your answer in terms of g, m, K, M and h. NOTE: Question 4.2 b) and c) on next page.
