5 stars for the best answer to this physics problem please show your work and espalain.?

the answer is 1.70m just show how do you get it from the physics formula and explain? !!!!! -The human body can survive a negative acceleration trauma incident(sudden stop) if the magnitude of the acceleration is less than is 250 m/s^2 (approximately 25 g).if you are in an automobile accident with an initial speed of 105 km/h (65mi/h) and are stopped by an airbag that inflates from the dash-board. over what distance must the airbag stop you for you to survive the crash?

1. v^2 = 2as 105 km/h = 105/3.6 m/s = 29.17 m/s s = v^2 / 2a = 29.17 ^2/ 500 = 1.7 m
2. x=v^2/2a=29.1^2/500= 1.7m so minimu dist = 1.7m
