Watching a Ferris wheel? An observer stands 20 m from the bottom of a 10-m-tall Ferris wheel on a line that is perpendicular to the face of the Ferris wheel. The wheel revolves at a?rale of ?? rad/min and the observer’s line of sight with a specific seat on the wheel makes a ? n angle? with the ground (see figure). Forty seconds after that seat leaves the lowest point on the wheel, what is the rate of? change of? ? Assume the observer’s eyes are level with the bottom of the wheel.

Step-by-Step Solution:

Solution: Step 1 To find Forty seconds after that seat leaves the lowest point on the wheel, what is the rate of change of Step2 Given that An observer stands 20 m from the bottom of a 10-m-tall Ferris wheel on a line that is perpendicular to the face of the Ferris wheel. The wheel revolves at a rale of rad/min and the observer’s line of sight with a specific seat on the wheel makes an angle with the ground Step3 Step 4 Step5 Therefore,Forty seconds after that seat leaves the lowest point on the wheel, 0.038 rad/sec is the rate of change of .
