RE: Velocity Question (Science/Math)
I'll do it for ya. Took physics last year. just hold on tho

Basically, what I can see is that there is two equations:
(let's hope they're right!)
8t=sin(Θ; )Vt + 12
2=cos(Θ )Vt
solve for the minimization for V

hmm dodgy theta's

anyways, I solved for t in each equation, then set them equal to each other.

V = 8/(6cos([Image: theta.bmp]) + sin([Image: theta.bmp]) )

graphing this gives
[Image: graph1.bmp]

and differentiating
dV/d[Image: theta.bmp] = -8*(-6sin([Image: theta.bmp])+cos([Image: theta.bmp]))/(6cos([Image: theta.bmp])+sin([Image: theta.bmp]))^2

solving for critical points gives [Image: theta.bmp] = arctan(1/6) or or .0029 degrees. The corresponding velocity comes out to be 1.315 m/s


ya, ya its different, but I might have messed up the equations at the beginning
