A girl on the outer edge of a merry-go-round moves in uniform circular motion. Which of the following is NOT correct?

A. Her speed is constant.
B. Her direction is constantly changing.
C. A force constantly pulls her toward the center of the merry-go-round.
D. She moves in a constant elliptical path.

Answer 1

i think that from the answers above the answer is B.

Answer 2

This is a poor question. I think they want you to choose D because the girl is traveling in a circular path. But a circle is an ellipse. So technically D is also true.
