- hi, not sure if its a bug but for "Projection (angle, height and distance) Calculator"
"l"formula no matter how i actually put in those number by hand or transpose onto a computer do not line up. the distance is indeed correct but not too sure about the formula. if the formula is correct was wondering if you could think of any reason why my computer and hand may not be interpriting it correctly? - from Keisan
- The "l" formula can be obtained as below.
i) l = v*cosθ*t
l2 = v2*cos2θ*t2
ii)
0 = v*sinθ - (g*t/2)
v2*sin2θ = (g*t/2)2
From i) and ii),
l = sqrt(v2 - (g*t/2)2) * t
