An auto race takes place on a circular track. A car completes one lap in a time of 11.6s, with an average tangential speed of 56.9 m/5. Find (a) the average angular speed and (b) the radius of the track.A fisherman is reeling in a fish. In 5.9 s he winds 3.8 m of fishing line onto a reel whose radius is 3.4 cm (assumed to be constant as an approximation). The line is being reeled in at a constant speed. Determine the angular speed of the reel.A compact disc (CD) contains music on a spiral track. Music is put onto a CD with the assumption that, during playback, the music will be detected at a constant tangential speed at any point. Since VT = rm. a CD rotates at a smaller angular speed for music near the outer edge and a larger angular speed for music near the inner part of the disc. For music at the outer edge {r = 0.0568 m]I_. the angular speed is 3.37 rew's. Find {a} the constant tangential speed at which music is detected and lb} the angular speed {in revls] for music at a distance ol'DDSoB m from the center of a CD
