I believe your kids are in out classes and report cards are coming out soon, aren't they?

The 185 teachers said:
Mr Fink has had 34 drinks, if he drinks 17 more he will have drunk exactly half as many drinks as Mr Martini. How many drinks has Mr Martini had?

Methinks your maths has come up short...  Good one though.

I find the uphill section the most intriguing. Not something you see a lot in water slides.
|
|
|
|

Agreed... skeptical how that could work for any generic rider, and how does water flow UP the slide at that section?

I don't remember about these things, physics classes seem like a million years ago. I'd imagine that cross-sectional area is a better indicator of weight than height is. That is to say, when travelling feet first, your diameter will be roughly proportional to your weight ergo, as weight goes up, so does air-resistance. If that's the case, then items of different sizes will still behave in a similar manner. Same terminal velocity, same safety considerations. Naturally, calculations like these can often prove to have counter-intuitive results.
If you drop 2 steel balls of different sizes you'll get the same terminal velocity since the cross-sectional area to weight ratio is the same. If you make them a different shape, the equality is lost. If you make them a different density, the equality is lost yet again. Variations in either will naturally result in variations of results. Since the body has a small frontal cross-sectional area, is made of the same stuff and is moving relatively slowly, reasonably large differences in weight will result in negligible differences to final speed. Far less-so than the variation observed by rolling different cars down the same hill, for instance.
As for the water flowing up - Same way any ballistic projectile moves against gravity - momentum.

Water also has (like most ballistic projectiles) the tendency to keep their momentum and direction. It's hard to change the course. Downward momentum + gravity means that it'd need a strong boost to change it's mind about going down.

Yep, I'd sure be interested in the in the curvature of the slide as it sent the rider and water back upwards. I reckon that if load cells were placed under each of the supports, those that were in the initial stages of the upward section of the hump would perhaps show 3x (or more) the weight that the others did.
Dangerous equations to get wrong, but quite enjoyable and cathartic to work through I imagine.

Maybe I'm wrong because physics classes was a while ago for me too, but weight is weight. It doesn't depend on cross sectional area or height, but mass instead. The gravitational force would be greater for more mass/weight, and hence objects of different mass will behave differently on that slide. Like you said, if weight goes up, air resistance increases (I agree), but I think there are other factors that cause it to not be purely proportional to weight (e.g size).
RE: water flowing up, yes momentum does the trick, but I think it's fair to assume that a large portion of the water would also splash up instead of flow up, thus losing momentum as a body of water. Water only behaves like a ballistic projectile if it remains as a single body of water. Everytime water sprays/splash, the nature of the "projectile" changes. I guess it depends on how smooth the ROI is on that slide angle. And then for water to flow back DOWN smoothly, the point of the second peak must be approximately Fg = Fn, which is hard to believe that this would be consistent for all riders.
Meh... I guess if this ride was built, it is functionally and physically sound/safe to ride on. Forgive me for being skeptical.

I have to agree with the comments that the sides aren't high enough. Not for me, either.

Mental. Not for me.
If there is one thing more dangerous than getting between a bear and her cubs it's getting between my wife and her chocolate.

If you are going to ride on something then why bother with the water? Just make it a regular slide.
- I would love to change the world, but they won’t give me the source code.
