The "reaction time" of the average automobile driver is about 0.7 . (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 12.2 .
A.) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 14.6. (in a school zone)
B.) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 54.2.
