Let us assume that rocket only runs in initial energy and not using its own to flying.
Also , let upward direction is +ve and downward direction is -ve .
Initial velocity , u = 58.8 m/s .
Acceleration due to gravity , .
Final velocity , v - = 0 m/s .
We know , by equation of motion .
Hence, this is the required solution .
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.
