nah, it will work. but make it 2 feet, from my experience, anything above 2 is unnecessary and requires a big jump. and if you really need it taller you could use bricks and cinder blocks under it or just snow

probably. make sure you have a smooth transition and a decent amour of speed at the beginning

You definitely should just make sure to pump into the drop in

Bigger is better, to much speed is never a prob. If your building it, do it right the 1st time.

ep=mgh
=75(assuming you're around that)*9.81*1.524
=1121.3J

ek=1/2(mv^2)
1121.3=1/2(75v^2)
1121.3=37.5v^2
v^2=29.9
v=5.47ms
=12.24mph

even assuming huge friction you'll be going at least 6mph i'd say, so yeah i agree with the rest that would work.
