Question 546933
As you ride the Ferris wheel in park,your distance from ground varies sinusoidally with time.You are the last seat filled,and the ride starts immediately.Let it be the number of seconds that have elapsed since you got on.It take you 10 seconds to reach the top,56feet above the ground.the diameter of the wheel is 50 feet. sketch the graph nd write an equation to represent your distance from ground.
-------------
h(t) = 31 - 25*sin(2pi*t/20 + pi/2) h in feet, t in seconds
= 31 - 25*sin((pi*t + 5pi)/10)
--------------
Notice that you board the ride 6 ft above the ground.
