A disk of radius 2.05 m rotates about its axis. Points on the disk\'s rim undergo tangential acceleration of magnitude 2.71 m/s2. At a particular time the rim has a tangential speed of 1.51 m/s. At a time 0.923 seconds later, what is the tangential speed, v, of a point on the rim, the magnitude of the point\'s radial acceleration, ar, and the magnitude of its total acceleration, atot?
