Hi(adsbygoogle = window.adsbygoogle || []).push({});

I'm having trouble figuring this one out..based on an angular momentum lab.

In the lab we had a turntable with a ball on it, when the ball was released, the intial velocity could be calculated using the formula

[itex]v=d(g/2h)^{1/2}[/itex]

I need to be able to derive the same formula

[itex]v=d(g/2h)^{1/2}[/itex]

using only measureable quantites from my lab.

measure quantities are

height (ball to table top)

mass of the ball

distance between axis of rotation and ball

distance horizontal distance

I have to derive this equation using horizontal and vertical coordinates.

any ideas?
