In outer space two identical space modules are joined together by a 500.0 massless cable. These modules are rotating about their center of mass. In each module, the cable is connected to a motor,so that the modules can pull each other together. The initial tangential speed of each module is v=17.0 m/s. The modules then pull together until the distance between them is reduced by a factor of two. a) Determine the final angular speed for each module. b) Compute the work done in reducing the cable's length.
