Two boxes are attached by a taut line that is threaded over a pulley of radius 13 cm and mass 100 g. The larger box has a mass of 849 g and lays on a level surface with friction coefficient 0.24. The smaller box has a mass of 341 g and sits on a frictionless incline of grade 0.82.

(a) What is the acceleration of the boxes?

(b) What is the maximum mass for the larger block so that it slides?

(c) If the pulley were massless, what would the acceleration of the boxes be?

(d) What is the maximum mass for the larger block so that it slides with the massless pulley?

Two identical spring scales are each attached to a cord that is wrapped around a pulley, as shown in Figure 1. The two pulleys have identical mass MpMp and radius RpRp. However, Pulley AA is a solid disk, whereas Pulley BB has most of its mass located at its outer rim. Both pulleys can rotate about their centers with negligible friction in their axles. The pulleys are initially at rest when the two spring scales are pulled with the same...

Two blocks are connected by a light string that passes over a frictionless pulley having a moment of inertia of 0.0040 kg*m2 and a radius of 5.0 cm. The coefficient of kinetic friction between the table top and the upper block is 0.300. The blocks are released from rest. Using energy methods, find the speed of the upper block just as it has moved 0.600 m.

A string is wrapped around a pulley with a radius of 2.0 cm and no appreciable friction in its axle. The pulley is initially not turning. A constant force of 50 N is applied to the string, which does not slip, causing the pulley to rotate and the string to unwind. If the string unwinds 1.2 m in 4.9 s, what is the moment of inertia of the pulley?

Two masses are connected by a light string, which passes over a frictionless pulley as shown in fig .3 on a the chalkboard. The inclined plane is rough. When m1=10kg , m2 = 3.0 kg and theta = 60degrees, the 10 kg mass moves down the inclined plane and accelerates down the nclined pane at a rate of 2.0m/s^2. Find a) the tension in the string. b)the coefficient of kinetic friction between the 10 kg mass and the inclined plane.
