Fun kinematics problem =)

  1. Oct 20, 2007 #1
    a car is moving at 56km/h when a deer jumps onto the road 65m ahead. after a reaction time of t seconds, the driver applies the brakes to produce an acceleration of -3.0m/s^2. what is the maximum reaction time allowed if the car is to avoid hitting the deer?

    It may be "fun" to solve that kinematics problem, but why exactly did you post here? If you have any doubts or want help to solve the problem, you have to show some previous effort on trying to solve the exercise (forum rule).
