A 40.0-cm diameter disk rotates with a constant angular acceleration of 2.60 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) At t = 2.44 s, find the angular speed of the wheel. rad/s (b) At t = 2.44 s, find the magnitude of the linear velocity and tangential acceleration of P.

linear velocity	m/s
tangential acceleration	m/s2

(c) At t = 2.44 s, find the position of P (in degrees, with respect to the positive x-axis). counterclockwise from the +x-axis
