Math Problem: Want me to take you seriously?

I heard the people of Offtopic love solving basic math problems. Here's one that a fellow b.net user gave me. It's literally a 10th grade physics problem (or so I'm told, I haven't studied shit like this in years, but I was still able to solve it pretty quickly). Anyways, what does this question have to do with me? If you kids can solve it (showing full work, of course), then I might actually show you some respect in our next debate/take you seriously. Even if you don't want that, at least try to show off your intelligence. Here it is: A body at rest slides with negligible friction from point A (has height h1+h2) down a smooth curved ramp. The end of the ramp is horizontal at point B (has height h1). The body then falls from point B to the ground. Show that the body will land at a distance d from point O (ground level and aligned with point B). Put your answer in terms of d, h1, and h2. PM me your work, but post just the answer on this thread. Purse, out.

    Well I mean what you're basically describing is some body on a ramp with height "h2" moving a distance down the ramp of d and finishing at a height of point h1. As you said there is no friction so there is no opposing force. The force downward would be the mass of the object X the acceleration and in this case it's just assumed that it's on earth so use g times the sin of the angle of the ramp. Anyway. You really never said the ground had friction so using the laws of the conversation of energy the body would move in a straight line once reaching the distance d and continue until hitting another object. Overall this "problem" is terrible. There isn't anything of substance here beyond understanding what it's asking you to picture.
