in terms of impulse and momentum, why are air bags in automoblies a good idea?
Umm... They're not. In any way I know of. They're terrible. The only concivable argument in their favor is paper bags have to have trees cut down to be produced and plastic doesn't but plastic sits in landfills for a century. In shorter terms, ditch plastic bags and if you feel bad about cutting down trees for your groceries go plant afew trees. Like, 10... We should have more trees.
