A ferris wheel has a diameter of 50 meters. If point A is at the lowest point of the ferris wheel, 0 meters. What is the height of point A if the wheel moves 2pi/3 radians clockwise? What is the equation?

Answer 1

since cos(x) has it max at x=0, and you have a min there,

A(x) = 50(1-cos(x))

now just plug in x = 2pi/3
