A 101 Frisbee is 22 in diameter and has about half its mass spread uniformly in a disk and the other half concentrated in the rim. With a quarter-turn flick of the wrist, a student sets the Frisbee rotating at 720 .What is the rotational inertia of the Frisbee? What is the magnitude of the torque, assumed constant, that the student applies?
A uniform solid disk with a mass of 23.8 kg and a radius of 0.712 m is free to rotate about a frictionless axle. Forces of 92.0 and 124 N are applied to the disk. Taking the clockwise direction to be the negative direction, what is (a) net torque pro..
