A merry-go-round (m = 500.0 kg and r = 5.0 m) is initially at rest and is put into motion. The merry-go-round is essentially a disk (I disk= 1/2MR^2). If the merry-go-round is being pushed by the parent in Figure (b) A. what is the magnitude of the angular acceleration experienced by the merry-go-round? B. If the merry-go-round is being pushed by the parent in Figure (b), and it attains a final angular velocity of 5.5 rad/s, how long did it take the parent to get to this final angular velocity? C.  If the merry-go-round is being pushed by the parent in Figure (b), and it attains a final angular velocity of 5.5 rad/s, through what angle did the merry-go-round rotate through during this change in velocity?
