1. Which of the following statements best applies to an object moving with uniform circular motion?(Answer: B) A. Acceleration is zero. B. Acceleration is directed outward. C. Acceleration is tangent to the path. D. Magnitude of acceleration is constant. I thought the answer was D but how can it be B? Centripetal acceleration is always towards the center of the circular path. How is that outward? 2. A 50kg man is riding a ferris wheel at a constant speed. At the top of the wheel, the seat exerts an upward force of 420N on him. What is the centripetal force on the man at the top of the wheel? (Answer: 70N) Fnet = FN+Fg+Fc 0 = 420+50(-9.8)+Fc 70N [up] = Fc Again, this direction has me confused. Centripetal force is always towards the center of the circular path so why am I getting an up answer?
