A 35g mass is attached by a string and rotates in a circle of radius 1.24m on a flat horizontal table as shown below. The mass starts out at a speed of 22 m/s and is slowed by friction. The coefficient of kinetic friction between the table and the mass is 0.17. (a) How much work is done by friction in slowing the mass to a stop? (b) What is the magnitude of the frictional force that slows the mass? (c) How many revolutions does the mass make before stoping? (d) What average power is dissipated by friction?

A hanging weight, with a mass of m1 = 0.370 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...

A mass of 150g is suspended vertically from a string that runs over a pulley and attached to a 100g mass on a rough horizontal surface. The pulley has a mass of 30g and a radius of 3.5cm. The string moves without slipping over the pulley while the masses move. The coefficient of kinetic friction between the rough surface and the 100-g mass is 0.05. Calculate the acceleration of the masses.

1. An object of mass 1.2 kg is attached to a string of 0.83 m. When this object is rotated around a horizontal circle, it completes 15 revolutions in 9.6 seconds. a. What is the period (T) of this motion? b. What is the tangential velocity of the object? c. What is the tension on the string?
