Power and work done

  1. Jun 21, 2011 #1
    can i say the work done on the punch of frighter??, i mean the force of the punch and the distance travelled by the punch.

    example, the force of punch is 100N and the distance for punch from the body to hit the target is 0.5m.

    work done = 100 X 0.5m = 50J
    and the power of the punch is 50j/ 2s(assumption) = 25watt
    can i say like that??

    anyone helps me.....thank you
