A disk having moment of inertia i = kg ? m2 is free to rotate without friction, starting from rest, about a fixed axis through its center. A tangential force whose magnitude can range from F = 0 to f = N can be applied at any distance ranging from R = 0 to r = m from the axis of rotation.
(a) Find a pair of values of F and R that cause the disk to complete th = rev in t = s.
(b) Is your answer for part (a) a unique answer? How many answers exist?
