A uniform disk of mass .53kg and radius 11cm is constrained to rotate on an axis about its center. On the disk are mounted masses of 9 grams at a distance of 8.14cm from the center, 22 grams at 4.95cm from the center and 35 grams at 3.41cm from the center. A uniform force of .08 Newtons is applied at the rim of the disk in a direction tangent to the disk. The force is applied for 3 seconds with the disk initially at rest.

Using energy considerations find the KE attained by the system.
