A 37.2-cm diameter disk rotates with a constant angular acceleration of 2.1 rad/s. 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. rad/s (b) Find the linear velocity and tangential acceleration of P at t = 2.30 s. linear velocity tangential acceleration m/s m/s c) Find the position of P (in degrees, with respect to the positive x-axis) at t = 2.30s.
