At this rate, you'll come 1st in the state in MX2 lol.lolokay said:say the projectile starts at the origin and has moved to point (x,y)
y = g/2v2cos[a]2 x2 + tan[a] x (from basic projectile motion equation. derive if necessary)
y' = g/v2cos[a]2 x + tan[a]
tan[@] = y/x
2y/x - tan[a] = g/v2cos[a]2 x + tan[a]
so 2tan[@] - tan[a] = y' (the direction of motion)
= y'
That's what I PM'd him about. haha.shaon0 said:At this rate, you'll come 1st in the state in MX2 lol.
Well its true.tommykins said:That's what I PM'd him about. haha.
Unless some olympiad guy beats him.namburger said:Thanks lolokay
You got 1 year of revision. Top in MX2 for sure =O
