Question by vinny2 · Jan 18, 2012 at 11:33 AM · physicstrajectory

Tracing a trajectory line

Do you guys know that trajectory line that Angry Birds has? Does anyone has any idea on how to do that? I have a similar setup here, but the physics is driving me crazy. How can i predict it?

My knowledge in physics hasn't been used for quite some time, but as far as I know, it must be like this:

v0 = Initial velocity a = angle

y(x) = (tan a) * x - ( g / (2 v0^2 cos^2(a)) ) x^2

This should give you the function that describes the trajectory line
