This is my problem.
I called the angle between ramp and horizontal theta.
Then, i formed a rectangle between V0 and the ramp, and found the angle between the ramp and V0 is also theta.
Then, i repositioned my coordinate system, so that the x-axis is parallel to the ramp's hypotenuse.
Then, i modeled:
(delta) x = V0cos(theta)* t + 1/2 g sin(theta) * t^2
(delta) y = V0sin(theta) * t + 1/2 g cos(theta) * t^2
and i plugged it into the pythagorean theorem.
when i solved for theta, i don't get a pure number, so i know its wrong.
need major help
