Howdy,
This is only for a second year course, but i didn't think it would get answered in the intro forums...
Ok, the wording of this question doesn't make much sense to me, but I assure you that this is what it says...
********************************************
Demonstrate how
x=A \cos (\omega t+\phi)
can be the answer for
E=\frac{1}{2}m\frac{dx}{dt}^2 + \frac{1}{2}kx^2
********************************************
I just don't see how this could possibly work. Any ideas would be helpful
-----------
As for my thoughts, I figured that either the question was written wrong, or that using the simplified energy eq'n (E=kA^2) would help...but I get nowheres using that still.
