A person with a mass of 76 kg is moving at a constant speed in a vertical circle on a Ferris wheel with a radius of 37.6 meters. If the difference between his normal force at the bottom (FNB) and the normal force at the top (FNT) of the circle is one third of his weight (FNB-FNT = 1/3 w), with what speed must the Ferris wheel be rotating in m/s? (What's the person's speed another words?)
