One of the oldest rides at an amusement park is the Merry-go-round. It is favorite of very young children, but
not exciting enough for high school age students. There is still much physics that can be studied with the Merrygo-round. Consider the following Merry-go-round. The inner radius of the rider’s platform is 10 ft. The outer
radius is 20 ft. There are four rows of animals to ride in that 10 foot distance on the platform. When the Merrygo-round is moving at full speed it takes just 40 seconds to make a complete rotation. Some of the horses on the
Merry-go-round move up and down in a periodic manner.
The horse on the innermost row of animals is located 12.0 ft from the center of rotation. The horse on the
outermost row of animals is located 18.0 ft from the center of rotation.
Answer the following as it relates to the above.
21. The person riding on the inner horse would feel an acceleration that is
a. zero once the ride gets up to speed
b. the same as the acceleration of a person on the outer horse
c. about 2/3 the acceleration of a person on the outer horse
d. about 3/2 the acceleration of a person on the outer horse
