Homework Help: A Question on impulse

1. Apr 18, 2005

I have an easy question about Impulse $$J$$: Is it safer in a car crash to have a bigger impulse or a smaller impulse?

What does your instinct say?And why?

It doesn't really work that way.Usually the time of impact (the time in which momentum is being transfered) is rather small,making the effects even larger...

The only way to have a smaller impulse is to have a smaller change in velocity. Perhaps you mean: for a given crash impulse, or change in momentum, is it safer to have to have a longer or shorter duration for that impulse?
