That's very cool, thank you again. It actually matches my drawing, which is nice. I'm wondering though, because their orbits actually overlap, would their closest points be if they theoretically collided? From what I understand this isn't possible...and so my new dilemma lies in where to assume...

Thanks! I can't seem to figure out how to rotate one of the ellipses but I can try to visualize it.

I don't know how to use a spreadsheet plotting function... I'm going to attempt to draw out the two ellipses properly to visualize where the farthest and closest points should be and then I suppose I'll have to sort of guess what angle that will be and use the calculated R lengths to solve for...

The Sun I believe it supposed to be this solar system's Sun. No there's no software available. It's for an intro astronomy course in university. The only other info I was given was that the use of spreadsheet might be helpful in solving the problem. So I'm assuming I just have to go through and...

Do you think it would be possible to use radians/year and go through different amounts of time to find the least and greatest amount of angular distance between the two planets? Then maybe I could plug the angles into that polar form equation to find the distance (using cosine law).

No that wasn't provided. I do have mean angular motion though. n=2pi/P and for Q = .012045292 and for R = .022677567. I'm not sure what the units are though...is it radians/year?

Homework Statement Two planets are orbiting the sun in elliptical orbits in the same plane. The orbit of planet Q has a semi-major axis of 64.8 AU and eccentricity of 0.445. Planet R has a semi-major axis of 42.5 AU and eccentricity of 0.825. The perihelion point of Planet R's orbit is...

I actually tried 158 L just as a guess and it was still wrong... Is that what you meant? 1 m^3 = 1000 L .158 m^3 = 158 L

Homework Statement Original Question - A fishing boat displaces 3.31×10e3 kg of liquid when floating in fresh water (ρ=1000 kg/m3). If salt water has a density of 1.05×10e3 kg/m^3, how many kilograms of water would the boat displace if it were floating in salt water? ==> answer is 3.31e3 kg...

that would give the acceleration during t=10.2 s and t=26.9 s...which is different from the acceleration during t=0 s to t=10.2 s

but say x_0 and v_0 are both 0...you're still left with two variables... ie x = 52.2a well that's for the first section t=0 to t=10.2

I just need help getting started with this question. A 1350.0 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 10.2 s, then the motor stops. The rocket altitude 26.9 s after launch is 2210.0 m. You can ignore any effects of air resistance...

ya got it nevermind

[SOLVED] kinenatics (NOT cst acceleration) I have no idea how to solve a problem that doesn't have constant acceleration. I'm guessing you have to set up an equation using the given values and solve for the variable..but I don't know. This is the question anyhow: You're driving down the...

umm this question seems simple enough but I don't really know what I'm doing... A chain consisting of 5 links, each of mass .100 kg is lifted vertically upwards with a constant acceleration of 2.50 m/s^2. Calculate the force that link 2 exerts on link 1. so what I did was add the masses...
