How Do You Model Building Sway with Trigonometric Functions?

[runicle]

this is my question:
A Building sways 55cm to the right from origin in 5 seconds and 55 cm to the left of the origin in 35 seconds. And i am supposed to write an eqaution to define this.

I'm guessing the is no amplitude no vertical translation and since it's sine basically I am going to need some help...

Does anyone have any resources of GOOOD LIABLE EASY TO FOLLOW MATH SKILLS? My book Nelson Mathematics 11 with the rollercoaster in the front has a bunch of errors and misconceptions.

Do you mean reliable?(not sure how liable comes into play)

What concepts are you looking for and maybe we can show you a link to one online. Also see what your book says and maybe it is actually correct and you aren't grasping the concept.

I find it unlikely that your instructor would give you a book with multiple errors and "misconceptions".

It's a very weird question. I think you are looking for rotational kinematics here, as there is no translational motion. Why don't you express angular displacement as a function of time? In any case, the question seems too imprecise and vaugue to be a physics question to me.

First off its supposed to be solved using trigonometry and i figured out the question to today. Please note Key words like "guessing".

I'm not sure I'm clear on what you're saying. You definitely have an amplitude - 55 cm. You also have 30 seconds between the positive peak and negative peak (which is which depends on whether you decide 'right' is positive or negative). You also have a phase shift, since the building should sway left and right at the same rate.
