Jumping physics problem

  1. Dec 10, 2009 #1
    1. The problem statement, all variables and given/known data
    An exceptional standing jump would raise a person 0.80m off the ground. To do this, what force must a 66 kg person exert against the ground?
    Assume the person crouches a distance of 0.20 m prior to jumping,and thus the upward force has this distance to act over before he leaves the ground.



    This question i dont even know how to start
    can some one explain how to even start it?

    Re: Jumping

    Work = Force * Distance
    Force = (9.81)(66)
    Work = (9.81)(66)(.80)
    Work = 517.968 J

    Doesn't account for the crouching distance, but it may be irrelevant, someone else will probably cover that. I hope I went in the right direction with this.
