So if you have a block sitting on top of a frictionless slide(it's a ramp, so it goes down like a slide, levels out at the bottom at point A, then curves back up and ends at point B.)the height at the top of the slide is 3.91m, and the mass of the block is 1.62kg, the angle at point B is 45 degrees from the horizontal(err, in case that wasn't clear, at point B the block goes flying off at 45 degrees)and the height of point B is not given
so anyhoo, it wants to know the force exerted on the block by the track at point A(where it levels out) wouldn't that just be mg? That seems too simple though. Same thing at point B but with some trig fiddling to get like cos(45)*mg. I guess it COULD be that simple, there's two more parts to the problem that are giving me LESS problems just because I'm not second guessing myself, but I dunno.
Edit: I guess that doesn't really make sense though. In that case the force is constant, but obviously as you go faster and pull up like that, you're applying a greater force down(and hence the track is pushing up harder)
