Water from a fire hose is directed horizontally against a wall at a rate of 50.0 kg/s and a speed of 42.0 m/s. Calculate the magnitude of the force exerted on the wall, assuming the water’s horizontal momentum is reduced to zero.

Step-by-step solution In this problem water from a fire hose is directed horizontally against a wall.Now, calculate the magnitude of the force exerted on the wall assuming water’s horizontal momentum is reduced to zero. Step 1 of 4 If m is the mass and is the time interval, then the value of is, The horizontal speed of the water from the hose is, When the water touches the wall, the speed becomes zero. So, Step 2 of 4 Substitute for and for
