Question

(c9p4) A wheel starts from rest and rotates about its axis with constant angular acceleration. After 8.9 s have elapsed, it has rotated through an angle of 10 radians. What is the angular acceleration of the wheel? What is the angular velocity when the time $t = 8.9$ s? What is the centripetal acceleration of a point on the wheel a distance $r = 0.40$ m from the axis at $t = 8.9$ s?
