During a certain time interval, the angular position of a swinging door is described by e = 4.92 + 9.4t + 1.99t2, where e is in radians and t is in seconds. Determine the angular position, angular speed, and angular acceleration of the door at the following times. (a) t = 0 rad w = rad/s a = rad/s2 (b) t = 3.05 s rad w = rad/s a = rad/s2
