Chapter 2, Problem 83P

* Data from state driver’s manual The state driver’s manual lists the reaction distances, braking distances, and total stopping distances for automobiles traveling at different initial speeds (Table 2.11). Use the data to determine the driver’s reaction time interval and the acceleration of the automobile while breaking. The numbers assume dry surfaces for passenger vehicles.

Table 2.11 Data from driver’s manual

Speed (mi/h)	Reaction distance (m)	Braking distance (m)	Total stopping distance(m)
20	7	7	14
40	13	32	45
60	20	91	111
