# Tracing a trajectory line

 0 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? more ▼ asked Jan 18 '12 at 11:33 AM vinny2 46 ● 9 ● 9 ● 10 just look up basic projectile ballistics on google for millions of diagrams, equations etc Jan 18 '12 at 02:58 PM Fattie add new comment (comments are locked) 10|3000 characters needed characters left ▼ Viewable by all users

 0 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 = angley(x) = (tan a) * x - ( g / (2 v0^2 cos^2(a)) ) x^2 This should give you the function that describes the trajectory line more ▼ answered Jan 18 '12 at 11:51 AM LestatTom 1 ● 1 ● 1 ● 1 Do you gave a more specific example?
