A stream of water flowing horizontally with the speed of 15m/s gushes out of a tube of cross-sectional area 10-2m2 and hits a vertical wall nerby. What is the force exerted on the wall by the impact of water assuming it does not rebound?

We know that speed of water is 15m/s so we can assume the tube height to be 15 m. Are of cross section is given... So volume of the cylinder(water flowing) can be calculated
Volume=0 .15 m^3
Density=mass/ volume.as density of water is 1000 kg/m^3..... Mass of water is 150 kg.
Force=mv-mu
=150(15) -150(0)
2250 N
