Your instructor rides on a merry-go-round turning at a constant rate. In which direction does the net force on your instructor point?

Question

A. away from the center
B. toward the center
C. down
D. tangent to the circular path

I choose D.tangent to the circular path (wrong again)

Answer 1

B. Centripetal acceleration goes inward, so it follows that centripetal force would do the same.

The velocity of the horses and everything is tangent to the circular path, though.
