Yes i think so!!!
i think..
your totally right Angi.
Explanation:
The given data is as follows.
Fluid is water so, density
Weight flow rate = 500 lbf/s = 2224.11 N/sec
Cross-sectional area (A) =
= 0.05184
Hence, weight flow rate will be given as follows.
w =
2224.11 N/sec =
V = m/s
= 4.373 m/s
Thus, we can conclude that average velocity in the given case is 4.373 m/s.

Your "weight" is the name you give to that gravitational force.
So your question actually says:
"Your weight just got three times stronger !
What happens to your weight ?"
Answer: 14. 49 m
Explanation:
We can solve this problem with the following equations:
(1)
(2)
Where:
is the horizontal distance between the cannon and the ball
is the cannonball initial velocity
since the cannonball was shoot horizontally
is the time
is the final height of the cannonball
is the initial height of the cannonball
is the acceleration due gravity
Isolating from (2):
(3)
(4)
(5)
Substituting (5) in (1):
(6)
Finally:
