Car B is traveling a distance d ahead of car A. Both cars are traveling
at 60 ft/s when the driver of B suddenly applies the brakes, causing
his car to decelerate at 12 ft/s?. It takes the driver of car A 0.75 s to
react (this is the normal reaction time for drivers). When he applies
his brakes, he decelerates at 15 ft/s?. Determine the minimum
distance d between the cars so as to avoid a collision.

A driver travelling at 50mph sees a hazard (boulder) at a certain distance ahead. The
driver then applies the brakes immediately (PIEV) time is 2 seconds and begins slowing
the vehicle at 10m/sec? (decelerating). If the distance from the stopping point to avoid
hitting the boulder is 10.28m, how far was the car from the boulder upon perception?
