Homework Statement
A fireman's hose acting as a water cannon, directs 100 litres/s (100 kg/s) of water horizontally at your chest at speed 5 ms-1. Assuming water essentially falls to the ground after hitting your chest (rather than say reflecting horizontally backwards), what horizontal force will you feel (in N)
Homework Equations
Impulse = change in momentum = Ft
p = mv
The Attempt at a Solution
Hello. I do not know where to start from in this question. How do you get the mass from 100 litres/s and how would you to calculate force when not given a value for time for impulse?
Help is greatly appreciated!
