    Calculating Force on a Man from Variable Mass Water Jet

    The problem is that I know the rate of change of mass but not the rate of change of velocity. Edit: nevermind I think I got it.

    Calculating Force on a Man from Variable Mass Water Jet

    ok, so I replace dm with ρAv0dt. I still have the same problem.

    Calculating Force on a Man from Variable Mass Water Jet

    Homework Statement Water with mass density ρ are being shoot from a jet with cross sectional area A and velocity v0 at a man with mass m0. 1. Find the force acting on a man at rest (assume all the water are absorbed in the clothes) 2. Find the force acting on a man escaping at velocity v<v0...
