Aprox 373.205 ft. See below
Explanation:
Supose the center of the wheel in coordinates oringin.
This wheel rotates 360º every 30 min. So in 17,5 min will rotate 210º because: the direct proportionality of rotation in a time interval
Starting rotation at the lower position, the cabin will be at 60º to be in horizontal postion and at 200 ft to ground. Thus, applying trigonometry
Given that the time period of rotation of LW is
So angular frequecny of rotation
The diameter of the wheel is
Let the mimimum height of the wheel seat at the moment to hop on for boarding it at
For
