what kind of math would be involved in calculating the maximum speed of a zipper?

was pretty bored and i was zipping my zipper and im actually curious to know now

102 MPH.

what if metal zippers are sturdy enough to be fastened at any speed but the zipper itself gets so hot from friction it melts?

make it out of carbon.

sounds like a good answer to many things

just spray some WD40 on it

The hardest part may be figuring out the function for zipping a zipper. From there just basic calculus. Find the derivative equal it to zero. And find the absolute max.

Nifty question! You'd have to look at how the zipper connects to each other. (and ignore the material part for now. Outside of friction, that's a different question all together.)

As the pulling force is mostly going in a different direction then the attachment function, you would have a particular limit for which the rate could actually occur at.

A rough guess would be that the total force used to move the "zipper" portion would get divided up at least twice, and as such you would get to play with 2 values of angular momentum... So, at certain specific speeds, the changes would be sufficient to prevent the zipper from attaching, but at higher speeds, it may fix itself... ^_^

The some second order correction to the speed of sound in metal. To be fair, if the zipper can't break and you're allowed to put arbitrarily much energy in, the speed of light, but no.
