- A student holds a bike wheel and starts it spinning with an initial angular speed of 9.0 rotations per second. The wheel is subject to some friction, so it gradually slows down. In the 10.0 s period following the inital spin, the bike wheel undergoes 77.5 complete rotations. Assuming the frictional torque remains constant, how much more time At, will it take the bike wheel to come to a complete stop? Ats = S The bike wheel has a mass of 0.825 kg and a radius of 0.315 m. If all the mass of the wheel is assumed to be located on the rim, find the magnitude of the frictional torque 7† that was acting on the spinning wheel.

- 2. A wheel of radius 20 cm is initially rotating at 12 rpm. It then speeds up at a constant rate, reaching a speed of 35 rpm after 3.1 seconds. a) What is the angular acceleration of the disk? b) How much does it rotate (in radians) while it is accelerating from 12 to 35 rpm?" c) What is total acceleration (in m/s?) of a point on the edge of the disk at the moment it has just started accelerating?|An electric fan is turned off, and its angular velocity decreases uniformly from 450 rev/min to 220 rev/min in a time interval of length 4.50s. a) Find the angular acceleration α in revolutions per second per second. b) Find the number of revolutions made by the fan blades during the time that they are slowing down in Part A. c) How many more seconds are required for the fan to come to rest if the angular acceleration remains constant at the value calculated in Part A?Problem 12: A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 1.3 meters, and a mass M = 241 kg. A small boy of mass m = 46 kg runs tangentially to the merry-go-round at a speed of v = 1.8 m/s, and jumps on. Randomized Variables R = 1.3 meters M = 241 kg m = 46 kg v = 1.8 m/s
