Force Ramp problem

  1. May 5, 2009 #1
    1. The problem statement, all variables and given/known data
    what is the net force acting on a 1.6t car initially parked on a smooth icy road banked at 40o. (frictional forces are negligible)


    2. Relevant equations
    Fd=mgsin[tex]\theta[/tex]


    3. The attempt at a solution
    I'm not too sure.
    1600 x 9.8 x sin40

    but it = the wrong number?? help!

    I believe you at least have a problem with units. What is the "ton" thing in terms of mks units? It's good to get in the habit of carrying units along in your equations, and multiplying and dividing them out just like you are doing with the numbers. If you are calculating a force in mks units, the answer's units had better be in kg*m/s^2, right?
