Thank you! I found the aphelion and perihelion and plugged it in an equation from there

I have another quick question if you don't mind me asking. The next part of the question is asking for eccentricity of the orbit. Now I know I can figure this out if I figure out the minor axis. Is there an equation to find out the minor axis by knowing the major axis? I'm looking online and I...

holy ****ing ****. I just entered it and it accepted it. You just walked me through the problem without me even realizing it... Thank you so much.

The axis I have drawn is long, or the major axis? So I'm looking for the semi-major axis? and that would be half of it?

Like this? if yes, I'm not sure what axis it lies on, but its total length should be: earth's orbital radius plus mars' 149,943,160km + 228,189,693 km = 378,132,853 km. But I'm not sure what that gives me.

I think I need to find out the aphelion and perihelion but I am not sure how. And gneill, I'm not exactly sure what you're asking but If you mean the radius that the ellipse makes, would it be the diameter of Earth's orbit + the radius of mar's?

Homework Statement Hi, I have a question on my homework that I'm absolutely stuck at. I'm not sure how to go about this. Can someone help me through the steps to solve it? there are more after this similar to it so learning how to do this one would help me do the other ones by my self. Thanks...

i ended up solving backwards for the constant he used and got 6,400^3. I used that in the problem and got the right answer. Thanks for the help though.

Yea i understand what you mean, but the problem is that the test is online and unless I get the precise answer, I can't move on to the next question. which is a terrible system. I guess I need to find out what constants the professor used to reach that number in the example problem.

Hmm, but what i don't understand is, you got 7700 m/s for 350 and for the example problem, it says 7697.5. Is the teacher doing something differently?

if i did it right, i got 7.674861 km/s or 7674.861 m/s, however, it is telling me it is also wrong...

So then she is right because the mechanical advantage does change because as you pull the rope, you are also getting higher?

So basically, at my work at a science center, we have this exhibit where you lift yourself using different pulleys. I noticed that the pulleys were labeled wrong. They should have been, 1/2, 1/3, and 1/5 but were labeled, 1/3, 1/4, and 1/6. I brought this up with management and received an email...
