A Person Riding a Ferris Wheel Is Strapped into Her

A person riding a Ferris wheel is strapped into her seat by a seat belt. The wheel is spun so that the centripetal acceleration is g. Select the correct combination of forces that act on her when she is at the top. In the table, F_g = force of gravity, down; F_b = seat belt force, down; and F_s = seat force, up.

A) F_g = 0, F_b = mg, F_s = 0
B) F_g = mg, F_b = 0, F_s = 0
C) F_g = 0, F_b = 0, F_s = mg
D) F_g = mg, F_b = mg, F_s = 0
E) F_g = mg, F_b = 0, F_s = mg
