Practice coming straight at it at a low speed until you consistently have it, then try shortening the angle until you can come at it parallel and with decent speed

Tbh it’s just practice and use a flat surface. Once you get used to the movement then try getting out of it.

You're probably not getting the impact right, try getting some speed on flat ground and nosestalling on a curb, go faster and faster until you've memorized the way it feels to counteract the force, then try it on the ramp.
