## [answered] A string is wrapped around a uniform disk of mass M = 1.1 k

A string is wrapped around a uniform disk of mass?M?=?1.1?kg?and radius?R?= 0.11 m?(see figure below). Attached to the disk are four low-mass rods of radius?b?=?0.15?m,?each with a small mass?m?=?0.7?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?=?22?N?for a time of?0.2 s.?Now what is the angular speed of the apparatus?

Also calculate numerically the angle through which the apparatus turns, in radians and degrees.

??degrees?=( ?)?
