a) knowing that the diameter of the Ferris wheel is 100 ft, determine the angular speed (in rad/s) of the Ferris wheel.

b) Determine the linear speed (in ft/s) of the rider on the Ferris wheel. (Hint: Use the equation for arc length L=θr, where L is the arc length, θ is the angle of the arc, and r is the radius. Realize that the equation for circumference of a circle is the equation for arc length with an arc angle of 2π).

c) If the ride is 5 minutes long, how many linear feet does the rider travel during the ride?

d) There are a total of 12 cars on the Ferris wheel. When exiting the ride, the rider of the interest has to wait for 2 other cars to empty until they exit the ride. How many extra linear feet are traveled during exit time? (Hint: Use the equation for arc length).

(a) 1.5 revolutions is 3 pi radians, and that takes 60 seconds. Compute 3 pi/60 as for the angular speed. Call it w.

(b) w*D/2 is the rider's speed.

(c) Multiply the speed from (b) by 300 seconds

(d) 1/6 radian * (D/2)
