Question

A ferris wheel is 40 meters in diameter and boarded from a platform that is 1 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 8 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn.

What is the Amplitude? ____ meters

What is the Midline? y ___ meters

What is the Period? ____ meters

How High are you off of the ground after 4 minutes?  ___ meters



Answer 1

h (t) = 21 + 20 sin [(2π / 8)t − π/2]

1. 20 meters
2. y= 21 meters
3. T= 8 min
4. h(4) =41 meters
