A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to 0(t)=yt + ßt ³, where y = 0.420 rad/s and 3 = 0.0140 rad/s³.
▾ Part A Calculate the angular velocity of the merry-go-round as a function of time. Express your answer in terms of the variables ß, y, and t.
▾ Part C Calculate the instantaneous value of the angular velocity w, at t = 4.70 s. Express your answer in radians per second. 15. ΑΣΦ | ▼ W₂ = Submit Part D Request Answer Way-z = B ? Calculate the average angular velocity Wav-z for the time interval t = 0 to t = 4.70 s. Express your answer in radians per second. 15. ΑΣΦ rad/s ? rad/s
