Transcribed Image Text:

A uniform disk with mass m = 9.15 kg and radius R = 1.38 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 325 N at the edge of the disk on the +x-axis, 2) a force 325 N at the edge of the disk on the -y- axis, and 3) a force 325 N acts at the edge of the disk at an angle 0 = 34* above the -x-axis.
