Auniform disk with mass m = 8.88 kg and radius r = 1.3 m lies in the x-y plane and centered at the origin. three forces act in the +y-direction on the disk: 1) a force 335 n at the edge of the disk on the +x-axis, 2) a force 335 n at the edge of the disk on the –y-axis, and 3) a force 335 n acts at the edge of the disk at an angle θ = 33° above the –x-axis.
1) what is the magnitude of the torque on the disk about the z axis due to f1?
2) what is the magnitude of the torque on the disk about the z axis due to f2?
3) what is the magnitude of the torque on the disk about the z axis due to f3?
4) what is the x-component of the net torque about the z axis on the disk?
5) what is the y-component of the net torque about the z axis on the disk?
6) what is the z-component of the net torque about the z axis on the disk?
7) what is the magnitude of the angular acceleration about the z axis of the disk?
8) if the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t =1.5s?
