a disk having moment of inertia 100 kg ? m2 is free to rotate without friction, starting from rest, about a fixed axis through its center. a tangential force whose magni- tude can range from f 5 0 to f 5 50.0 n can be applied at any distance ranging from r 5 0 to r 5 3.00 m from the axis of rotation. (a) find a pair of values of f and r that cause the disk to complete 2.00 rev in 10.0 s. (b) is your answer for part (a) a unique answer? how many answers exist?
