A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s and the water strikes the door horizontally and doesnt bounce back. What average force is exerted by the stream of water?

Step-by-step explanation:

= Mass flow rate of water = 320 kg/s

= Mass of water on the door

= Time

= Velocity of water on the door = 20 m/s

Force is given by

The average force is exerted by the stream of water is .

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
