I'm confused with the range equation. I am using TBR and am unclear on a few concepts:
1) As I understand it, if the initial and final height of a projectile are the same (ex. it is launched on a field and ends on the same field), I can use the equation: r = (vo²Sin2theta)/g .
2) If the heights are different, which equation can I now use? Also, in one of TBR's physics sample problems, I believe they used the above equation for a cannonball falling over a cliff. I thought that wasn't the right equation.
