A disk having moment of inertia 99 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 = 50.0 N can be applied at any distance ranging from R = 0 to R = 3.00 m from the axis of rotation. (a) Find a pair of values F and R that cause the disk to complete 2.90 rev in 10.2 s. (Let F = 26.0 N be one half of the pair.) R = m (b) Is your answer for part (a) a unique answer? How many answers exist? ○ 1 pair ○ 16 pairs ○ 150 pairs an infinite number of pairs
