We have a vehicular accident with an initial speed of 125[km/h] where the driver is stopped by an inflated airbag. Over what distance must the airbag stop the driver for him to survive the crash if our bodies can only tolerate a sudden vehicle stop with a maximum acceleration magnitude of 220 [m/s2]? (b) In another accident, the air bags deploy and slow down the passengers gently. Safety standards suggest the bags produce a maximum acceleration am that lasts for only up to tm. Express the distance a person travels in coming to a complete stop in tm at a constant acceleration equivalent to am and the initial speed in algebraic form. Here, provide also the initial velocity expression.
