Of course there is, by the main theorem of physics1 we can assume that the acceleration is constant, [; a= v_{max} / t ;]. Which gives us a factor of two for the answer compared to constant velocity.

1 Thm: Any interesting quantity can be sufficiently approximated by the linear order.

Proof: If you object to that, please tell someone from the soft sciences. That has two advantages, you are not bothering physicists and you keep the soft sciences bogged down.

Which part, the claim that physicists know enough math to know when to ignore mathematical rigor in favor of physical plausibility or the claim that other scientists don't?

First, the point of physics is to model the universe using math. If it can't be made mathematically rigorous, it's just intuition, or a model that fails in certain cases.

Second, non-analytic functions can occur in nature.

And third, anyone who insults the "soft sciences" is just being a douchebag.
