1. The problem statement, all variables and given/known data A fire hose discharges water at a rate of 16.0 kg/s with a speed of 20 m/s. What magnitude of force is needed to hold the nozzle stationary? 2. Relevant equations Impulse= Change in Momentum, Momentum (p)= mv, velocity final=velocity inital + at 3. The attempt at a solution V= 20m/s + 9.81m/(s*s)= 29.81 M=(16.0kg)(29.81) =476.96 Since impulse is the force over time, I thought impulse should be the force needed to keep the hose stationary, but it's not. Any help in where I went wrong would be great! Thanks!
