Force is defined as the rate of change of momentum.
The initial amount of momentum is
because water stops when it hit the wall total change of momentum must be 
.
Now let's calculate the force.
We need to find
. This is the amount of water hiting the wall per second.
Our final formula would be:
And now we can calculate the answer:
The initial amount of momentum is
Now let's calculate the force.
We need to find
Our final formula would be:
And now we can calculate the answer:
