9.5 - CALC A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to (t) = yt + Br", where y = 0.400 rad/s and B = 0.0120 rad/s". (a) Calculate the angular velocity of the merry- go-round as a function of time. (b) What is the initial value of the angular velocity? (c) Calculate the instantaneous value of the angular velocity w, at t = 5.00 s and the average angular velocity Wy for the time interval t = 0 tot = 5.00 s. Show that waris not equal to the average of the instantaneous angular velocities at 1 = 0 and I = 5.00 s, and explain.
