A uniform disk with mass m = 8.98 kg and radius R = 1.33 m lies in the x-y plane

Question

A uniform disk with mass m = 8.98 kg and radius R = 1.33 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 300 N at the edge of the disk on the +x-axis, 2) a force 300 N at the edge of the disk on the y-axis, and 3) a force 300 N acts at the edge of the disk at an angle ? = 37 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?  

N-m

3)

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

N-m

4)

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

N-m

5)

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

N-m

6)

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

N-m

7)

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

rad/s2

8)

If the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t = 1.7 s?  

J
