Work done

  1. May 24, 2016 #1
    1. The problem statement, all variables and given/known data
    A man pushes a lawnmower with a force of 200N. If the vertical component of this force is 80N how much work is done in pushing the lawnmower 6.0m horizontally?

    2. Relevant equations
    Work=force x distance

    3. The attempt at a solution
    Firstly I have to find the angle to the ground at which the 200N force is directed.
    However i am not sure on how to do that.

    Make a sketch and remember Pythagoras

    Would the angle be 68 because inverse tan(200/80)

    68 radians ? No, degrees I hope.
    Never mind: once you have the angle, what are you going to use it for ?
    And: Sketch ?
