@KinzaN What kind of question is a tilde?

anonymous · Answer

$$x=\sqrt{\frac{ 2g (\Delta d)^{2}m }{ 2k(0.3\sin \theta-y)\cos^{2}\theta+\Delta dksin(2\theta)}}$$

Good answer, I'll take it--thanks.  LOL.

anonymous · Answer

$$x=\sqrt{\frac{ mgd }{ ksin(2\theta)}}$$

is this on a  pendulum?

anonymous · Answer

Haha, nah spring lab thing.  Projectile spring type of problem, just trying to figure out a general expression for x.

anonymous · Answer

For the first one, they assumed g was positive.  Doesn't matter, I don't think.

anonymous · Answer

In the first one...what is y?  LOL.  Like where did that even come from...

anonymous · Answer

The second looks promising.
