A uniform disk can rotate around its center like a merry-go-round. The disk has a radius of 2.00 cm and a mass of 20.0 grams and is initially at rest. Starting at time t=0, two forces are to be applied tangentially to the rim in. One clockwise the other counterclockwise. At time t=1.25s the disk has an angular velocity of 250 rad/s counterclockwise. The clock wise force has a magnitude of 0.100N. What is the magnitude of the counterclockwise force?
