question 70

Multiple Choice

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.Here, 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
