The disc weighing 5 kg was tied with an unextended elastic cord of 0.5 m in length, as shown in the figure. As the disk passes through point B, its speed is vB=5 m/s and the length of the elastic cord is r=1.5 m. a) Determine the speed of the disc when r = 1.2 m, b) the shortening speed of the elastic cord when r = 1.2 m.
