A wheel 1.60 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.35 rad/s2. 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 angular speed of the wheel rad/s (b) the tangential speed of the point P m/s (c) the total acceleration of the point P magnitude m/s2 direction with respect to the radius to point P (d) the angular position of the point P rad
