Arotating wheel has a constant angular acceleration. it has an angular velocity of 5.0 rad/s at time t=0 s, and 3.0 s later has an angular velocity of 9.0 rad/s. what is the angular displacement of the wheel during the 3.0-s interval?
(a) 15 rad
(b) 21 rad
(c) 27 rad
(d) there is not enough information given to determine the angular displacement.
