Answer:
The achievement of lifting a rocket off the ground and into space can be explained by Newton's third law of motion. What is required for a rocket to lift off into space? Thrust is required for a rocket to lift off into space, ... An object that travels around another object in space is called a satellite.
Explanation:
To solve this problem we will use the linear motion kinematic equations, for which the change of speed squared with the acceleration and the change of position. The acceleration in this case will be the same given by gravity, so our values would be given as,
![m= 89 kg\\x = 3.1 m\\t = 0.5s\\a = g = 9.8m/s^2](https://tex.z-dn.net/?f=m%3D%2089%20kg%5C%5Cx%20%3D%203.1%20m%5C%5Ct%20%3D%200.5s%5C%5Ca%20%3D%20g%20%3D%209.8m%2Fs%5E2)
Through the aforementioned formula we will have to
![v_f^2-v_i^2 = 2ax](https://tex.z-dn.net/?f=v_f%5E2-v_i%5E2%20%3D%202ax)
The particulate part of the rest, so the final speed would be
![v_f^2 = 2gx](https://tex.z-dn.net/?f=v_f%5E2%20%3D%202gx)
![v_f=\sqrt{2(9.8)(3.1)}](https://tex.z-dn.net/?f=v_f%3D%5Csqrt%7B2%289.8%29%283.1%29%7D)
![v_f = 7.79m/s](https://tex.z-dn.net/?f=v_f%20%3D%207.79m%2Fs)
Now from Newton's second law we know that
![F = ma](https://tex.z-dn.net/?f=F%20%3D%20ma)
Here,
m = mass
a = acceleration, which can also be written as a function of velocity and time, then
![F = m\frac{dv}{dt}](https://tex.z-dn.net/?f=F%20%3D%20m%5Cfrac%7Bdv%7D%7Bdt%7D)
Replacing we have that,
![F = (89)\frac{7.79}{0.5}](https://tex.z-dn.net/?f=F%20%3D%20%2889%29%5Cfrac%7B7.79%7D%7B0.5%7D)
![F = 1386.62N](https://tex.z-dn.net/?f=F%20%3D%201386.62N)
Therefore the force that the water exert on the man is 1386.62
