A uniform circular disk of mass 10 kg and radius 10 m is free to rotate about a fixed axle perpendicular to it, passing through the center. It is acted upon by two forces in the clockwise direction. One has a magnitude of 10 N and acts at a distance of 1 m from the center, and the other has a magnitude of 20 N, and acts at a distance of 5 m from the center. The points of application of the forces lie in the same direction from the center (meaning a line segment can be drawn from the center to the edge of the circle, containing both the points of application of the forces)
(a) If the disk starts from rest, what is angular velocity after 1 minute?
(b) What is the magnitude of force on the disk by the axle about which the disk rotates?
