Question

If a ferris wheel with a radius of 25 feet and a center at 30 feet above the ground is rotating at 0.25 radians per second, define a formula for a function g that represents Shawna's height above the ground (in feet) in terms of the number of seconds since the ferris wheel started to rotate if she starts at the 9 o'clock position.

Answer 1

The axle is at height 25+5=30, so since ω = 0.25,
g = 30+25sin(0.25 t)
