Jeff, running outside to play, pushes on a swinging door, causing its motion to be briefly described by 0 = 9.5t² + 0.750t + 1.75, where t is in seconds and is in radians. At t = 0 and at t = 1.50 s, what are the following? (a) angular position of the door e(0) = rad (1.50) = rad (b) angular speed of the door co(0) = rad/s w(1.50) = rad/s (c) angular acceleration of the door a(0) = rad/s2 a(1.50) = rad/s2
