Question

A 44.3-cm diameter disk rotates with a constant angular acceleration of 2.3 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.

w=wi+alpha*t

wi=0
alpha = 2.3rad/s^2
t=2.3sec
solve for w.
