For the water bucket on a spring: I'm kind of sad they used Bernoulli's without mentioning that it is derived in an inertial frame. In the frame of reference of the cup, the pressure at the nozzle will oscillate around ##\rho gz##. It will inevitably be a function of ## \frac{dv}{dt} ## and ##z## itself. I would have liked to see how they neglected it professionally. I would say they hand waived it away, but actually they didn't address that at all. I'm sure it's a fine assumption for all practical purposes, but I would have liked to see it regardless for my own future reference.bob012345 said:I only referenced them so the OP can have them to compare with not that the problem has to be addressed exactly like these. It doesn't even look like these two do the same treatment anyway so I think there is still room for fun.
