A 41.0-cm diameter disk rotates with a constant angular acceleration of 3.00 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. At t = 2.37 s, find the angular speed of the wheel. (in rad/s)
a) 6.72
b) 8.43
c) 10.18
d) 12.05
