I just thought of this beautifully ugly question I just perceived and need to make it ...
it will be on an M3 familiar scenario ...
A particle will be slightly disturbed from the top of a surface whose cross section is in the shape of ( ...have not decided on the curve yet ...)
Find the distance the particle travels until the instant it leaves the surface

I will put hyperbolics and arclengths ...


sounds like a nightmare

Yay we solved exactly the same way :biggrin: Wonder if there is another way?

I swear I didn't copy yours or anything - I simply tried all the SUVAT equations that allowed me to manipulate yx \frac{y}{x}. :redface:

I think there might be one using calculus and differentiating a function of displacement. I was looking to do that, but it'd give me way too many variable to take care of!

No not accusing you :biggrin: I was happily surprised I used the same method as someone with such expertise in solving forum questions :3

Hmm interesting - wonder if someone else will attempt like that

Not sure if mine is particularly different to your two's, but it's attached anyway.

Hahahaha, I just looked over yours and saw that it's pretty similar. Did you use a calculator though? Flattery will get you nowhere by the way :colondollar:

I think using energy also looks feasible now that I think about it. TeeEm will probably use something cooler than SUVAT

Almost the same! :biggrin: :five:

Nah no calculator - hence why it took a while to compute the tan(theta + pi/6) haha

Very nice observation that it occurs at maximum height. I could never attempt it without a diagram, though.

I did have a diagram on the other side I just didn't scan that side since it was a scrap of paper and so was full of a load of random scribblings.

Pretty much :redface:
