A small car with mass 0.660 kg travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m (Figure 1). If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N, what is the normal force on the car when it is at the bottom of the track (point A)?

Follow-up Question

You are wrong. The normal force at the bottom is 18.95 N. You neglected to read the question completely and realize that speed is constant and thus velocity does not change. Thank you for nothing.
