vertical ... 2[5 sin(θ)] / g = t
... h = 5/2 sin(θ) * t/2
horizontal ... d = 5 cos(θ) t
2h = d
5/2 sin(θ) t = 5 cos(θ) t
dividing by cos(θ) t
and multiplying by 2/5
tan(θ) = 2
substitute back to find t

I don't really get you scott
Am I to substitute it this way 2[5(sin2)]/9.8.? Or will I make use of tan instead, since tan=2
Do tan-1 to find theta (how do you guys make a theta on this thing). Sub that back into the very first eq to find t
