A wheel 1.65 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.10 rad/s^2. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3° with the horizontal at this time.
At t = 2.00 s, find the following:
(a) the total acceleration of the point P
magnitude
direction
(b) the angular position of the point P
