Your are riding on a Ferris wheel that is rotating with a constant speed . The car in which you are riding always maintain its correct upward orientation , it does not invert.
a. What is the direction of the normal force on you form the seat when you are at the top of the wheel ?
i. upward ii. downward .iii. impossible to determine
b. From the same choices, what is the direction of the net force on you when you are at the top of the wheel?

Explanation

a. The normal force is always perpendicular to the surface that applies the force because your car mainlus its orienation at all points on the ride , the normal force is upward
b. Your centripetal acceleration is downward towards the center of the ciccle , so the force on you must be downward
