Hmmm. Or, speed up? That would be a lot of mass to oppose...

The idea that the sauropod could lead with it's chin, which is a
considerable distance from 'all that mass' seems a little suspect.

I was thinking chest not chin...

Then there is that "speed up" idea. THEY WERE SLOW. Unless you want to
engage in special pleading relative to nerve transmission speed and
muscle composition/capability, that is the presumption.

At those masses the momentum would still be great even if slow.

Although they might have made great sumo wrestlers.
