Homework Help: How do i determine power generated be an applied force

  1. Oct 29, 2005 #1
    Does anyone know how to answer this question?

    Question: How do i determine power generated by an applied force if it takes 9.0 s to push the box up the ramp.
    I am given
    height of ramp= 2.7m
    length of ramp= 5.3m
    angle= 30*
    constant force= 12N
    What should i do im stuck:surprised ! tell me what equation i should use. Please

    First calculate the work done in pushing the box the distance you want.
    W=Force * distance

    then remember that power is simply work done divided by time.

    So basically i just divide the work by 9 seconds and i get j/s as its unit?

    J s^-1 are indeed the units of power :).
