1. The disk is rotating about its central axis like a merry-go-round. The rotational position 0(t of a reference line on the disk is given by 0(t) = -y – ốt + Et² where y = 1.0 rad, 8 = 0.60 rad/s, and § = 0.25 rad/s² (a) Determine the angular position of the reference line at 0.0 s and 4.0 s. (b) Find the time when 0 is 0.0 rad. (c) Evaluate the angular velocity at 0.5 s and 1.5 s.
