    Finding the distance given the intital velocity and the coefficient of friction

    Well, my teacher told the class that we should only need equations from the kinematics and dynamics unit, so I've been trying to stick to those things. (I have to turn this in, so I would like to follow his instructions as much as possible, for the sake of my mark)

    Finding the distance given the intital velocity and the coefficient of friction

    Ffriction= -mgµ Is what I got... But how does it cancel out??

    Homework Statement A car is traveling at 15.5m/s travels on a surface where μ=0.1. The driver sees a boy run into the road 125 m ahead. She immedietly applies the brakes, locking the wheel, and skids to a stop. Where will the car be when it stops? (i.e:Will it hit the boy?) I know I should...
