Homework Help: physics - stopping distance

Posted by gladys on Thursday, April 25, 2013 at 12:03pm.

when a driver brings a car to a stop by breaki.g as hard as possible the stopping can be regarded as the sum of reaction distance and breaking distance. tje following data are given, v1 m/s contains 10,20,30. reaction distance are 7.5, 15, 22.5. the breaking distance are 5.0, 20, 45. and thr last are 12.5, 35, 67.5. a) what is the reaction time around? b) what is the stopping distance if the velociry is 25 m/s?


need the ans. asap
