Force And Energy

  1. Jun 2, 2007 #1
    1. The problem statement, all variables and given/known data

    Assume that force the force required to walk from home to school is on a 70 degree angle to the horizontal surface. This force is equal to your weight.
    mass is 120lb or 48 kg
    a) calculate weight.

    3. The attempt at a solution

    a)
    w=mg
    w=48kg*9.8N/kg
    w=470.4N
    IS THAT RIGHT?????????

    470.4 N is the right weight. Now how much for does it take to push that weight up a 70 degree incline? I think that's the question.

    b) calculate the mangitude and direction of the force that causes you to move in the horizontal direction.
