    We've just started Energy and I'm having a bit of trouble.

    Here's the question:

    How much work is done by a football player pushing an opponent with a force of 700 N [E] for a displacement of 2.0m [E]?

    Would someone please post the answer and the solution. Thanks.

    well, Work Done = Force x Displacement

    So the answer would be (700x2)J

    Wouldn't it be in Joules if it's energy, not Newtons?


    Edit: Nevermind, it's force not energy...my bad XD

    Assuming you guys aren't using the trig cosine, the above poster is right...

    Work Done = Force * Displacement

    X = 700*2
    x= 1400 Joules
