The "reaction time" of the average automobile driver is about 0.70 ss. (The reaction time is the interval between the perception of a signal to stop and the application of the brakes.) An automobile can slow down with an acceleration of 11.8 ft/s2ft/s2.

Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 16.4 mi/hmi/h (in a school zone).Express your answer in feet.

Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 54.2 mi/hmi/h.Express your answer in feet.
