So, air bags don't really help. a. In what sense is his argument true(What equation for impulse?) b.) Draw 2 diagrams of a passenger during a crash. Show the position deceleration of the person starts and stops clearly with versus without airbags. c.) Why is his argument misleading?( Equation for impulse to use to know the effect of a crash on your body.) How do air bags help?
