Question

A ferris wheel turns at a constant speed. the lowest point of the wheel is ground level. a person is standing on a platform 4m about ground. The intervals between two successive times are alternatly 6 s and 18 s. Part A) what is the period of rotation? Part B) what is the raduis of the wheel? Part C) graph the function?

Answer 1

A) 18-6 = 12 seconds
B) no idea of the radius. You give no indication of the height of the wheel, or where the platform is in relation to the axle.
C) no can do. All we know is that

h(t) = A + Bsin(pi/6 t + C)
