A uniform disk with mass m = 9.44 kg and radius R = 1.32 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 318 N at the edge of the disk on the +x-axis, 2) a force 318 N at the edge of the disk on the –y-axis, and 3) a force 318 N acts at the edge of the disk at an angle θ = 35° above the –x-axis.

3) What is the magnitude of the torque on the disk about the z axis due to F₃?

What is the z-component of the net torque about the z axis on the disk?

What is the magnitude of the angular acceleration about the z axis of the disk?

If the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t = 1.8 s?
