Chapter 1.2, Problem 34E

Velocity of a Ferris Wheel Use Figure 7 as a model of the Ferris wheel called Colossus that is built in St. Louis in 1986. The diameter of the wheel is 165 feet. A brochure that gives some statistics associated with Colossus indicates that it rotates at 1.5 revolutions per minute and also indicates that a rider on the wheel is traveling at 10 miles per hour. Explain why these two numbers, 1.5 revolutions per minute and 10 miles per hour, cannot both be correct.
