Question
The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.0 cm and a mass of
22 grams and is initially at rest. Starting at time t-0, two forces are to be applied tangentially to the rim as indicated, so that at time t-
1.2 s the disk has an angular velocity of 240 rad/s counterclockwise. Force F₁ has a magnitude of 0.105 N. What is magnitude F₂?
