Calculate the mangitude and direction of the force

  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.

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

    3. The attempt at a solution

    plz helpppppppppppp

    F_x = mg*cos(70)

    =48kg*9.8N/kg*cos (70)
    is that right
