Homework Help: HP & Cats

  1. Mar 11, 2010 #1
    1. The problem statement, all variables and given/known data
    A 4.50 cat leaps from the floor to the top of a 97.0-cm-high table. If the cat pushes against the floor for 0.230 to accomplish this feat, what was her average power output during the pushoff period? Answer in terms of horsepower.


    2. Relevant equations
    W = Fdx
    F = ma


    3. The attempt at a solution
    I'm not even sure where to start

    How much energy did the push give the cat? Do you know the equation for gravitational potential energy?

    No, I"m not sure what the equation for gravitational potential energy is...

    nevermind! I figured it out!

    P.E. = 9.8(4.5)(.97) = 42.777J

    42.777/.23 = 185.987W

    & 746W = 1hp

    185.987/746 = .249hp
