Work and Power

  1. Jun 3, 2009 #1
    1. The problem statement, all variables and given/known data
    A 100kg man climbs a vertical 10m ladder in 12s.
    How much work is done by the man?
    What is the man's power output?


    2. Relevant equations
    For the work I think I need
    W=F.s and F=(change in momentum)/time

    I've got no idea what the equation for power is though.


    3. The attempt at a solution
    Work = force x 10

    Use Eg = mgh to find how much work the man does.
    Then use mikelepore's indicated site to calculate power.
