Question

A human being cannot tolerate acceleration of much more than a few hundred m/s^2 without sustaining serious permanent injury. If the acceleration is sustained for more than a few seconds, the maximum tolerable acceleration is much less. Suppose a car is initially moving at 33.0 m/s and then is quickly stopped in a collision.

A) What is the minimum time over which the driver must be decelerated in order that he not experience an acceleration of magnitude greater than 9.40*10^1 m/s^2? Assume constant acceleration.

B) What is the minimum distance the driver must be allowed to move forward during the deceleration?
