(a) A 4.29 kg salami is supported by a cord that runs to a spring scale, which is supported by another cord from the ceiling (see Figure (a)). What is the reading on the scale, which is marked in weight units? (b) In Figure (b) the salami is supported by a cord that runs around a pulley and to a scale. The opposite end of the scale is attached by a cord to a wall. What is the reading on the scale? (c) In Figure (c) the wall has been replaced with a second 4.29 kg salami on the left, and the assembly is stationary. What is the reading on the scale now? (a) (b) Spring scale (c) (a) Number Units

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

A spring (which behaves linearly both in tension and compression) when tested vertically in isolation, as shown in Figure 1, is found to stretch by x0 cm when it supports a mass of m1 kg. Figure 1 The spring extends by x0 cm when supporting an m1 kg mass The spring, along with a damper, is then attached horizontally to a trolley of mass 1360 kg, which is constrained to move only in the x-direction (see Figure 2). The spring is stretched some distance from its equilibrium position before being released. (a) (b) Figure 2 (a) A frictionless trolley is attached by a spring, with spring constant k and a damper with a damping coefficient χ. The trolley is shown in its natural rest position with its left-hand face at x = 0. (b) Free body diagram for the trolley shortly after being pulled to the right then released, with the spring under tension so, at this instant, its velocity is in the negative x-direction. (For clarity the damping force and normal reaction forces have been shown as acting at the point of their arrows - the spring force and weight are shown as acting at the tail of their arrows.)
