A Golf swing's force

  1. Jan 17, 2009 #1
    In a typical golf swing, the club is in contact with the ball for about 0.0011 s. If the 45 g ball acquires a speed of 63 m/s, estimate the magnitude of the force exerted by the club on the ball.

    What are your thoughts on the problem? What have you tried thus far?

    i was trying mv^2/t
    i think its actually mv^2/ t^2

    No, neither of these are correct; why do you think so? You are given m, t, and the speed of the ball after impact; you need to first identify the speed of the ball before impact, then find the average force of impact, using the proper equation that relates force with mass, speed, and time. What is that equation?

    i worked backwards with the anwser i was given but i messed up and put a divid sign in there

    the eqution i got was mv^2t^2
    but i have some doubts about the anwser.

    I think we have to check the whether before we start the game. Working backwards may work. i didn't try it.

    yeah, you just have to try and relate acceleration to speed and time and then acceleration to force
