Astring is wrapped around a uniform disk of mass m = 1.2 kg and radius r = 0.07 m. (recall that the moment of inertia of a uniform disk is (1/2)mr2.) attached to the disk are four low-mass rods of radius b = 0.11 m, each with a small mass m = 0.5 kg at the end. the device is initially at rest on a nearly frictionless surface. then you pull the string with a constant force f = 29 n. at the instant when the center of the disk has moved a distance d = 0.039 m, a length w = 0.023 m of string has unwound off the disk.(a) at this instant, what is the speed of the center of the apparatus? v = ? m/s(b) at this instant, what is the angular speed of the apparatus? w1 = ? radians/s(c) you keep pulling with constant force 29 n for an additional 0.022 s. now what is the angular speed of the apparatus? w2 = ? radians/s
