d)use your equation to find the height of the rider after 10 seconds
h(t) = -25.25cos(pi*t) + (2.5+25.25)
t is in minutes.
10 seconds = 1/6 minute
---
h(1/6) = -25.25cos(pi/6) + (2.5+25.25)
= 5.883 meters above the ground

 e)How would your graph and equation change if the skywheel was set to a max speed of 1.5 revolution per min?
The period would be reduced.  The max and min points would be the same height but closer together.
