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 constant force FsFs, causing both pulleys to rotate. Predict which of the pulleys, if either, will complete one revolution first.

____ Pulley AA ____ Pulley BB ____ Both pulleys will complete one revolution at the same time.

Without writing or manipulating equations, provide reasoning for your selection.

A cord is wrapped around a pulley of diameter 0.320 m with the free end tied to a weight. That weight is allowed to descend at constant acceleration. A stopwatch is started at the instant when the weight reaches a speed of 0.023 m/s. At a time of t = 1.50 s, the weight has dropped an additional 0.080 m. Calculate the magnitude of the centripetal acceleration of any point on the circumference of the pulley at t = 4.0...

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?

A block is attached to a light string that is wrapped around a cylindrical spool. A) the spool consists of a uniform solid disk of radius r= 0.500m and a rim along the outside edge of the disk at a radius of r = 0.500m. The mass of the solid disk is mdisk= 4.00 kg and the mass of the rim is also mrm= 4.00 kg. What is the moment of inertia of the entire spool? B) the block is...
