Need Help with Car Brakes problem

  1. Oct 5, 2005 #1
    I just recently registered with this website and it is incredible! I cant believe how great it is. I stumbled upon here looking for help with a physics question my professor posed to us.

    If a car is coating down a hill and locks its front brakes, it will travel in a reasonably straight line. If it locked its back brakes, it would behave erratically. Why?

    I really cant think of a reason why this would be. Any help finding the answer would be much appreciated! thanks1 :smile:
