A Ferris wheel at a carnival has a diameter of 62 feet. Suppose it turns at a rate of 70 revolutions per hour.
(a) Find the angular speed of the wheel in radians per hour.
(b) Find the linear speed of a passenger in feet per minute.

Do not round any intermediate computations, and round your answer to the nearest whole number.,

Diameter of Ferris Wheel = 62 feet => r = 31 feet Rate of revolution = 70 rev per hr A. Angular speed of wheel in radians per hour is Rate of revolutions x 2pi radians Angular Speed = 70 x 2 x 3.14 = 439.6 radians B. Linear Speed = radius x angular velocity angular velocity = 439.6 / 60 = 7.33 So the linear speed = 31 x 7.33 = 227.12 feet/min
