Which has greater angular velocity, a horse near the outside rail of a merry-go-round or a horse near the inside rail?
The inside horse
The outside horse
Neither - they both have the same angular speed
I don't know
Which would have a greater tangential velocity?
Kid near the center of the merry go round
Kid near the outside of the merry go round
neither
Both kids have same tangential velocity
