According to the claims, the rocket lands back to a platform in the ocean. Now we will scientifically examine the accuracy of this claim.
It has caught my attention while watching the video, I am sure it caught the attention of many of you; the rocket did not come vertically, it had an angle. This can be demonstrated as follows, depending on the angle with the vertical:
As the rocket rises, it can be directed in the direction it will go. This is because the movement depends on the motor power. Speed is low during landing and engine power is intended to balance gravity. Therefore, engine power should have an angle to compensate for gravity. Lets try to make a solution. The problem is here:
here, the force provided by the engine power and the gravitational force must be equal or approximately equal in order to achieve a constant and decreasing rate of descent.
We define To the motor power (Fe) and the vertical component (Fev) of the motor power;
It should be; Fev = Fg
Fev= Fe . cos α
herefrom:
Fe. cos α = Fg.
The weight of Falcoln9 rocket is approximately 1900kgs.
Hence;
Fg = 1900kgs >
angle of inclination at the time the photo was taken :
Alpha= 20 degrees as follow;
So:
engines must apply the following force for a smooth landing:
Fe x cos α = Fg
so;
Fe = Fg / cos α = 1900kg / cos 20° = 1900 / 0,94= 2021 kgs.
that is, the engine must exert a force equivalent to 2021 kg to balance gravity.
In this case, we will have to calculate the horizontal components, since the vertical component forces will be balanced. I called it as F(h)
F(h) = Fe x sin α = 2021kgs x sin 20 = 691kgs.
we see that this force is not balanced. this force causes the rocket to spin under normal conditions.
Although I take the wind from opposite direction here, it will not prevent the spin movement. The reason for this is that the wind acts all along the rocket, but the component of the motor that causes the spin movement acts from a single point.
As a result, the rocket will spin and fall during such a non-vertical landing attempt. This physical evidence proves that this landing is not real.
Rockets also lift vertically during their first launch. After a while, their direction changes undesirably by wind and other factors. however, then the routers step in and slowly correct this error. a rocket does not have the technology to correct such a sharp angle in such a short time, and such a local and sudden wind situation cannot be predicted to correct the rocket's direction.
Conclusion: This landing movement does not comply with the laws of physics, it does not comply with natural flow of the life. but can be created as a simulation, Fake and cgi; or cgi and fake, or any or both of them.
Ellon Musk, his followers and NASA have trolled the world by this claim.
MUSK is failed!
