A42.0-cm diameter disk rotates with a constant angular acceleration of 2.70 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=2.30s.
(b) find the linear velocity and tangential acceleration of p at t=2.30s.
(c) find the position of p (in degrees, with respect to the positive x-axis) at t = 2.30s.

= Final angular velocity
= Initial angular velocity = 0
= Angular acceleration = 2.3 rad/s²
= Angle of rotation
