Forums rules state you have to atleast attempt the problem. I'll give you a hint though, you only need Newtons second law to solve this problem.

well, I found a rule in the textbook where R = (v*2sin(theta))/g, but I wasn't really sure if this works as it's for projectile cases and it doesn't show anything about h. I need to find the equation using the two dimensional rules formulas.
