- A 0.71-m-diameter solid sphere can be rotated about an axis through its center by a torque of 12.8 m∗N which accelerates it uniformly from rest through a total of 170 revolutions in 15.0 s. What is the mass of the sphere? Express your answer to two significant figures and include the appropriate units.Two bugs, Buzz and Crunchy, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 0.80 m and the disk is rotating with an angular speed of 38 rpm. The coefficient of friction between the bugs and the disk are μs = 0.80 and μk= 0.60. What is Crunchy's speed, in m/s?A thin- walled cylinder of radius 50 cm, mass 1.0 kg, is mounted on a frictionless, horizontal axle as in Figure 1 . A light cord wrapped around the wheel supports an object of mass 2 kg. When the wheel is released, the object accelerates downward, the cord unwraps off the wheel, and the wheel rotates with an angular acceleration. Find the angular acceleration of the wheel, , and the tension in the cord.
