1. The problem statement, all variables and given/known data
You are riding in a chair on a ferris wheel at constant speed. When you are at the the 3 o'clock position and moving upward (counterclockwise), which of the following statements must be true.

True The total force exerted on you by the chair is straight upward.
False The total force exerted on you by the chair is in a direction both upward and
inward toward the center of the ferris wheel.
False The total force exerted on you by the chair is in a direction both upward and
outward away from the center of the ferris wheel.
False Your acceleration vector is pointed directly toward the center of the ferris wheel.
True Your acceleration vector is pointed in a direction both upward and inward toward
the center of the ferris wheel.
False Your acceleration vector is pointed in a direction both downward and inward
toward the center of the ferris wheel.


Could someone just check my answers and let me know if I got them right.
Thanks

You are in uniform circular motion. Your only acceleration is inwards towards the center of the ferris wheel. Isn't it?
