Two tangential forces F₁ = 20 N and F2 = 35 N are applied to the rim of a solid disk of radius R
= 0.2 m. The disk starts to rotate from rest, and reaches angular speed of 1200 rpm in 10
seconds. (a) Find the magnitude and direction (plus for ccw and minus for cw) of angular
acceleration of the disk.
