The reaction time of the average automobile driver is about, Ask an Expert

Academics

The "reaction time" of the average automobile driver is about 0.7s. (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 11.0ft/s2.

A) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 12.0.

mi/h

B) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 50.8.
