Homework Help: Inclined Planes

  1. Oct 21, 2009 #1
    Hello there, I am having trouble with this question:

    A seal, mass of 82kg, jumps onto a horizontal ice float with a Vo of 6m/s i. The friction between the seal's belly and ice is 160N. g is 9.81m/s^2. How far does the seal slide?

    So so far, if I'm correct, I calculated the acceleration:

    Fnet=ma (i)

    a= Ffriction/mass


    And now I'm stuck. Do you need to find the time?

    Hello einsteinette! :smile:

    Use the work-energy equation … work done = change in energy. :wink:
