I think that it is A!

anonymous · Answer

Nvm. I was wrong. Its definitely C!

unklerhaukus · Answer

why would it have arccosine in it/?

unklerhaukus · Answer

or is that the amplitude times cosine?

anonymous · Answer

The basic equation for simple harmonic motion:
x = acos(wt)
where x is displacement from resting position (or d in this case)
a is the amplitude, which is the largest displacement the object can experience
w is the angular speed or angular frequency
and t is the time

So answer is c = acos(wt)
