Frictional force on the car

  1. Apr 5, 2005 #1
    A stationary car of weight W on a road sloping at 30 degrees to the horizontal. The frictional force on the car is 4000 N acting up the road BC.


    What is
    (a) the weight W
    (b) the normal contact force R of the road surface on the car?

    What exactly are you stuck on? You're gonna need to show evidence of having done stuff, as people aren't gonna do your homework for you!

    Well...the first part. I can't get the vector diagram right. Where do I put 4000 N to start with?

    Draw your picture with the road sloping down to the right, say. Then the frictional force points back up the road, up and to the left.
