**Damon**, Thursday, December 8, 2011 at 4:17pmcenter of wheel is 1 + 7 = 8 m above ground

cos (2 pi t/T) is max of +1 when t = 0

so h = 8 + 7 cos (2 pi t/T)

what is T, the period or time to go 2 pi radians?

speed = 10,000 meters/3600 seconds

= 2.78 m/s

distance around = 2 pi r = 2 pi*7 = 44 m

so

T = 44m/2.78m/s = 15.8 seconds

so

h = 8 + 7 cos (2 pi t/15.8)
