- 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 = r, 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), the angular speed is 4.44 rev/s. Find (a) the constant tangential speed at which music is detected and (b) the angular speed (in rev/s) for music at a distance of 0.0449 m from the center of a CD.A hyper car's report claims the car can reach 100 km/hr from rest in 2.8 seconds. We will assume that it has a constant acceleration over that time. Car's linear acceleration = 9.92 m/s^2 Assuming the diameter of a tire is 58 cm, find the angular acceleration of the wheel.help pls asap not in scientific notation pls
