A compact disk, which has a diameter of 12.0 cm, speeds up uniformly from zero to 4.00 rev/s in 3.00 s. What is the radial and tangential components of the acceleration of a point on the outer rim of the disk at the moment when its angular speed is (a) 2.00 rev/s and (b) 3.00 rev/s. (c) How far has a point on the rim traveled when the disk is rotating with an angular speed of 4.00 rev/s?
