the height in meters, of a passenger on a Ferris wheel is given by the function h(t)=11-10cos(0.1pit), where t is the time in seconds. How long will it take a passenger to reach a height of 5 meters the first time? Express your answer to 3 decimal places.

Answer 1

so
5 = 11-10cos(.1pi t)
cos (.1 pi t) = 6/10 = .6
set your calculator to radians
.1pi t = .927295
t = 2.95 seconds
