Homework Statement
Three forces of F1, F2, and F3 are applied to a solid disk with a mass of 3.6 kg and radius of 2.9 meters. F1 is directly above the center of the disk with a magnitude of 47 Newtons directed in the positive x direction, F2 is directly to the right of the center and has a magnitude of 47 Newtons directed in the negative y direction, and F3 is directly to the left of the center and is also directed in the negative y direction. If the disk is initially at rest and then rotates about its center 7 rotations counter-clockwise (positive direction) in a time of 13 seconds, what is the magnitude of F3 in Newtons?
Homework Equations
The moment of inertia for the disk about its center is I = 1/2 M R2.
The Attempt at a Solution
Answer comes to be 96.72. I have no idea how to get that answer
