Would i get enough speed for a 15 ft rail with my 5 ft drop in ?

[SacZiplock]

Title said it all , i'm gonna build my rail with pvc soon and my drop in is 5 ft tall , I'm wondering if it would be high enough to get enough speed for my a 15 rail ** during winter ** so id have snow .Thankkkkss !

probably. but it kinda depends on how high your rail is

but your most likely fine

 

[SacZiplock]

my rail would be like 2 - 3 feet tall , should i take it to 10 ft ?

 

[monkatizer]

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

Thanka bro! +K

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.
