ok so the other day i built a ramp that is about 5 and a half feet high. the hill that leads to it is 60 feet from the top to ramp. the angle is about 36 degrees at the top and the ramp is on an area about 10-15 degree pitch. the ramp is 43 degree so it will probably get me way up there. is there any way of knowing how far im going to go so i can build a down spot because if not id be landing flat.... this is my first time ever building a ramp and any help would be very much appreciated.
