Rotational Motion A ladybug with a mass of 5 walks around a flower at 33 1/3 rpm. If it uniformly slowed down and stopped in 5.5 seconds, what was the angular acceleration of the lady bug? Through how many revolutions did the lady bug turn as it came to a stop? Consider a merry-go-round which makes 20. revolutions in 4.0 min. What is the average angular speed in radians/s? For a child 3.5 m from the center, how far does he travel in the 4.0 minutes?
