Thanks for the insight sophiecentaur and WannabeNewton.
FYI, the only questions left are:
Also, does anyone know how to derive this equation below?
[tex]x=\frac { \pm \sqrt { { { v }_{ max } }^{ 2 }+{ v }^{ 2 } } }{ ω }[/tex]

and
[tex]θ(t)={ θ }_{ max }cos(ωt+ϕ)[/tex]
Does θ_{max} need to be in radians or degrees? It doesn't matter, does it? Will it matter if I take the derivative?
[tex]w(t)={ θ }_{ max }ωsin(ωt+ϕ)[/tex]
How can angular speed be a function of itself?
