29. A rigid body, starting at rest, rotates about a fixed axis with constant angular acceleration . Consider a particle a distance r from the axis. Express (a) the radial acceleration and (b) the tangential acceleration of this particle in terms of , r, and the time t. (c) If the resultant acceleration of the particle at some instant makes an angle of 57.0° with the tangential acceleration, through what total angle has the body rotated from t  0 to that instant?
