The "reaction time" of the average automobile driver is about 0.70 s. (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 10.6 ft/s2. 1) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 15.8 mi/hmi/h (in a school zone). Express your answer in feet. 2) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 57.4 mi/hmi/h. Express your answer in feet.
