i wish i could say i remember how to do this stuff:
ap = agsin(theta) This formula calculates the acceleration of the object as it slides down the incline. In situations without friction it would be the actual acceleration of the object. In situations considering friction, the acceleration of the object would be less than this value.
Not quite a roll-in, but same purpose: A platform-drop-to-landing. In the clip, dude says the first gap is 32 feet.
Makes me wonder exactly how tall (and what angle/transition) a regular roll-in (where you start at a standstill with no runup) would have to be to clear 32 feet on your first double..... Any physics/math nerdz in the house??
