Thomas Bradshaw invented the first Merry-Go-Round to be operated by a steam engine. If the engine
suddenly stopped, and the Merry Go Round experienced no friction or air resistance, how could the riders
on the ride slow its rotational motion?
Run toward the edge of the platform.
Run toward the center of the platform.
Jump off the ride all at once.
Lay down flat on the platform.
