A uniform disk with mass m = 8.55 kg and radius R = 1.35 m lies in the xy plane and centered at the origin. Three forces act on the disk in the +y-direction (see Figure 1 below): a force = 335 N at the edge of the disk on the +x-axis, a force F2 = 335 N at the edge of the disk y-axis, and a force F3 = 335 N at the edge of the disk in the +y-direction and at an = 30° above the -x-axis. F₁ on the angle F3 +y F2 ד F1 +X
(a) What is the magnitude of the torque on the disk due to F1?
(b) What is the magnitude of the torque on the disk due to F2?
(c) What is the magnitude of the torque on the disk due to F3?
(d) What is the magnitude and direction (clockwise or counterclockwise) of the angular ac- celeration of the disk?
(e) If the disk starts from rest, what is the angular speed and the rotational kinetic energy of the disk after the forces have been applied for t = 0.6 s?
(f) What are the radial and the tangential accelerations, the magnitude of the acceleration, and the tangential and radial components of the velocity of a point on the rim of the disk at t = 0.6 s?
(g) How many revolutions does the disk make during first 0.6 s?
