Momentum and Impulse
A good way to insure that an egg dropped onto a flexible surface will not break is to increase/decrease the stopping distance which will increase/decrease the stopping time?

probably. which do you think?
and that's "ensure" in this context, not "insure."

I know it’s increasing the stopping time so that force will decrease, but I’m not sure about distance, maybe increase the distance so there’s more time? But I’m not sure how that would tie into the formula I’m using for impulse over time = force.

I agree. Less force means more time taken to reduce the velocity. Since the same KE has to be stopped, that means more distance is needed to apply the force.
