Question

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

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.
