Self-studying Fundamentals of Astrodynamics.

No matter how i add/subtract/multiply/divide the vectors i can't get any of the numbers that show up as answers. Not even the r or v.

A little stuck on this problem:

Any help is much appreciated, i am trying to become an aerospace engineer entrapauneer that will move onto space engineering when the time is right.

Literally look up the definitions and plug the numbers in senpai. If you can't do this one by yourself, how will you manage Hohmann transfer orbits?

Which definitions do i look up Senpai?

Once i get a brief understanding of how the numbers interact i'll get it.
I'm slow to understand, quick to master kind of mind.

>I'm slow to understand, quick to master kind of mind.

I'm not that guy what the fuck is this kind of 'I'm retarded but I'm smart' shit. This is like people who now claim there are 8 types of intelligence because they were too retarded to get A+ in math.

How can you be quick to master if you are slow to understand? Do you mean that after you understand, you are quick to master? If so then you are not saying anything, if you already understood you already mastered. And if you understand something but think that you haven't mastered it then you don't understand it.

It means once an understanding of the basics has been grasped, the understanding of the advanced isn't far off when compared to others where the basic comes quick and the advanced comes slow

Don't think you understand the difference, you can learn a skill but take a while to master it, just having knowledge isn't always mastery,

Now i gave it a go and when i combine the specific mechanical energy in the x and y vectors i get something CLOSE to the answer but it is not the answer.

I believe it has something to do with z factor becuase it is only 9.27x10^7 off from the answer.

If i get help with this it will make my mind click for when it comes to finding the answers to the equations from the multiple vectors.

Any help is much appreciated ty

Are you bloody retarded? The question asks you to find the specific energy and momentum of the orbit. What do you think you should look up, the mating cycle of reindeer?

If there are more reindeer flying aronud the globe wouldn't that change the mass of the earth and thus the answer to the specific energy?

What if it is on a flock of reindoor orbiting the earth?

I hate it when textbook authors pull that 'it's obvious that...' shit. It just seems to me like it's the author stroking his cock while writing it.
