Question

The vertical motion of a seat on a Ferris Wheel can be described by the equation y=25cos(pit/3)+26 What is the period of the seat's motion in seconds?

Answer 1

I tried this:

Explanation:

Considering your equation I think it reads:

`y=25cos(pi/3t)+26`

where in the argument of `cos` appears the angular frquency `omega` that in this case is equal to `pi/3`.
The angular frequency is reated to the period `T` as:

`omega=(2pi)/T`

so using the value given we get:

`pi/3=(2pi)/T`

rearranging:

`T=2*3=6s`
