A 50.8-cm diameter disk rotates with a constant angular acceleration of 2.10 rad/s². It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time.

(a) Find the angular speed of the wheel at t = 2.30 s.

(b) Find the linear velocity and tangential acceleration of P at t = 2.30 s.

(c) Find the position of P (in degrees, with respect to the positive x-axis) at t = 2.30s.
