Speed check

So I just learned this awesome and super safe way to check if you're gonna have enough speed to clear a deck. Apparently it was in Transworld a while ago, but I learned it from some little snowboarder. But anyway, like most people I usually just hit it and hope for the best. But what I didn't know is that you can go like you normally would into the jump, but instead of hitting it, sideslip the deck, and if you make it, you know you'll have enough speed to clear it. Idk if other people already know about this, but I didn't and neither did most people I talked to.

Oh, and if people have tried doing that and it doesn't work please tell me/ everyone who reads this thread, but if you think about it, it makes perfect sense. Oh and the kid made it his 1st try. (it was at least a 45ft and the kid was maybe 11 and maybe 90lbs.)

Hmmmmmmmmmmmmmmmmmm,  seems like it would depend on how hard you sliped the deck to me.

Isn't that what everyone does. You see that all the time in movies/edits. I never done it personally though, I just go for it or check other people's speed.

no, that's dusting the jump, he's talking about going around and when you pass the lip of the jump dust the deck. It depends on how hard you slip, you could dig your edges in and completely stop or just gradually go along. Personally I like to dust the jump and look over the lip, it helps smooth out the jump to prevent ruts and you still get a good idea of speed. If the jump is built right, start your slide at the beginning and if you make it to the lip you're usually good.

i dont think its as simple as that because it depends alot on how hard you slip and whether the jump is a step down, step up or table

the best way is to watch someone who looks about your weight hit it or if he doesnt mind just follow him off it

Well I mean if it's a pretty small jump you don't really have to worry about casing too hard so it's not that big a deal. I saw this done for a kicker, but you're not supposed to stop, just side slip like you normally would.

The only thing I'm not really sure about is a step up. b/c it might not be possible to slip up the deck if there is one. But if you can, and you do make it, you'll definitely have enough speed.

orrr you could do what everyone else does and solve the equation vf^2=vo^2+2a(x-xo). and solve for x. where vi is you initial velocity, vf is your finaly velocity, which will be the same as vi due to the fact that our velocity on the x axis will not change (assuming we are hitting a true stepover) a is the acceleration and (x-xo) is the change in distance

like hockey stop(like when you snow someone), but instead of stopping you kinda just slide across the snow sideways.


but this idea this seems like it all depends on how hard u sideslip

Seems like this could work well. But it would take a little experimenting on your own. Say, take a jump that you can clear, or have been clearing. Then go sideslip the deck. Find out how much pressure you needed to sideslip the whole thing. That's (hopefully) the pressure you need. I'd go check it on a couple sized jumps as well.

no, you slide next to the jump, which is why it all depends on how hard you stop. I still think dusting the lip is a better way to go though.

just go with 2 times too much speed if you dont clear that one you will the next

No, you're not sliding the jump, you slide the deck, knoll whatever you wanna call it next to the jump, as for what issue I have no idea. It was a trick tip though so you might be able to find it that way.

False. Projectile motion is not the same as linear deceleration, let alone the difference in air friction versus ski-to-snow friction (along with the variable rate at which you will sideslip). I find it highly unlikely that these two outcomes have a positive correlation. At most, you'd be gauging your speed with the same inaccuracy as one would otherwise, and only creating an educated guess. Don't hurt yourself!

why would you solve for x? we know the distance of the jump and want to know the speed needed. where's gravity in this party of errors? a? and velocity is vector quantity, therefore is constantly changing. speed in a ideal environment would be constant along x, yes, not velocity. and we're gunna need some angles in there somewhere...

but yea i'd also like to know a good method other than waiting around for someone else to hit the feature or having an estimated guess for yourself at the how fast you should go

^ lol yeah thats great advice.  pretty sure there is a differece between ballsy and calculated risk  there buddy.

^It's not really about being ballsy or not, and there's no reason to be an asshole about it. It interested me and I though some ppl on NS might like to know. In reality, it's for jumps that are big enough that you may get seriously hurt by coming up short or going too big. So yeah it may not be the most badass thing but it's better than getting hurt speed checking. You don't need to try it but you really sound like an asshole when you're an asshole on threads that might help kids be better skiers

One time I was approaching the lip of a stepdown and realized I wasn't going to have enough speed so I thought I'd try to look baller and dust the lip. Well, I ended up catching an edge and commando rolling onto the flats. Its a good thing it was super soft I would've been fucked.

The best way to speed check a jump is following someone off who has hit it already, period.

but of course you would have to calculate your exit angle... then convert your velocity from magintude  cartiansian x and y values using ViSin(theta) for the y direction and ViCos(theta) for the x.  you also have to figure out the yf because yi and yf won't be the same. At the end you'll probably end up with 2 equations with 3 unknowns and decide "fuck it i'm just going to hit the damn thing" instead of doing that math.

Yeah,

Go up to the jump like you're going to hit it, but go past the actual jump and side slip the deck/knoll whatever you wanna call it.

If you make it across side slipping, then you know you'll have enough speed. If you fly off the other side you know you have too much.

This is really for bigger jumps that you're really not sure about. Like I said before, I saw this this summer when a little snowboarder wanted to hit the first big jump at COC. It worked for him, so there's no reason it shouldn't for other people.

^wait seriously?

Well if you are serious it's like stopping but without digging your edge in as hard so you slip insteaad of stopping.
