Caculation of force exerted by water

  1. May 21, 2012 #1
    Hi,

    I was standing in a river and I'm curious how much force it was exerting on my leg. I'm not sure how to do this calculation. Here's what I know:

    F=ma
    if the final velocity is zero, F=mv/t

    I'll assuming I was standing in 1ft of water, my leg is 36in^2, and the water is traveling at 4mph.

    It doesn't make sense that the force exerted over 2 seconds would be different then the force exerted over 4 seconds.

    Any suggestions or help?

    Thanks
