## Homework Statement

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?

## Homework Equations

Impulse= Change in Momentum, Momentum (p)= mv, velocity final=velocity inital + at

## 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!
