  1. A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to θ(t) = γt + βt3, where γ = 0.40 rad/s and β = 0.012 rad/s3
    1. Calculate the angular velocity of the merry-go-round as a function of time
    2. Calculate the average angular velocity ωavz for the time interval t = 0 to t = 4.0 s.
