An air bag is used to safely decrease the
momentum of a driver in a car accident. the air
bag reduces the magnitude of the force acting on
the driver by
(1) increasing the length of time the force acts
on the driver
(2) decreasing the distance over which the force
acts on the driver
(3) increasing the rate of acceleration of the
driver
(4) decreasing the mass of the driver
