yep it has five docking ports, I figured I'd fit as many as I could on it.

Launch Time: about 1:50
Team Members Present: Gareth
Play-by-Play: Initial stage with solid boosters and main sail fired. Solids exhausted, sperated, angling ship to 45° toward the water off of kerbal space center. Main sail burnt until in sub space. Main sail detached, poodle engaged. 45° angle maintained up till disired orbital height is reached. Positioned at 90° in direction of trajectory. Wait until apoapsis. Power up utill orbit is expanded to a realativly square orbit. Deployed solar panels and lights. Objective acheved
Time-of-Flight: about 38 hours
Summary: With this successful journey a manned space station and perhaps future refueling station has been put in place.
Opportunities / Learnings: How to get a large object out of the atmosphere and into orbit
Strategies / Project Timeline: Will perhaps try to send up some large fuel tanks to create a refuelling station and perhaps build on the space station

Vehicle Name: space station
Vehicle Parts List and Cost:
1 main sail
1 large fuel tank
6 solids
6 radial decouplers
2 medium tanks
2 decouplers
1 poodle
1 small tank
1 advanced sas
1 mk2 lander-can
6 structural beams
8 small rcs tanks
8 rcs boosters
5 docking ports
4 large solar panels

Launch Time: about 2:00
Team Members Present: Gareth and Clayton
Play-by-Play: launch, solid stage released, aim for orbit, main sail released, poodle used to create stable orbit, backwards burn at apoapsis to create reentry, reentry achieved slight regression burn to slow down ship, parachutes deployed, safe landing
Photographs:
Time-of-Flight: I think it was about a 2 days flight
Summary: The mission was a great success, the ship was recovered along with the kerbal. This was a momentous occasion for all of kerban.
Opportunities / Learnings: How to achieve a stable orbit and have a safe reentry to kerban
Strategies / Project Timeline: We will next perhaps try for the mun

Launch
Time: about 1:20
Team Members Present: Just Gareth
Play-by-Play: Solid Boosters Fired, First stage released, parachutes deployed, saftly drifts back to kerban
Photographs:
Time-of-Flight: about 30 min
Summary: Kerbal safely reached 10K meters and drifted back to kerban
Opportunities / Learnings: Staging and proper parachute deployment
Strategies / Project Timeline: We feel that we are ready to go for a manned orbit

So I should get (-lamda*r)/(2*pi*e0)+c for the electric potential right?
-
Hello,
I got to this question and was not sure how to go about it. I sorta had an idea but that was for the line charge of a fixed length, so do I just ignore the lengths and assume that E= lamda/(4 pi e0) and then use V=int(E*dl)?

Im on question 11 of the Web Assign.
I thought the right way to do it would be to take the added mass of the person, multiply it by gravity to get the force, and then use F=-kx to get the spring constant. Then use that with T=2pi sqrt(k/x) to get period and then 1/T = F to get frequency. Am I on the right track but just getting wrong numbers?

Is anyone else having issues with WA?
I can log in, but it just continuously loads when I try to open an assignment.

Well after some time the final version of the APlusPhysics app is here with loads more functionality than its predecessor. Now you can browse the entire community, post to the forms, write a blog, and post a comment. I also pulled together the videos off of aplusphysics.com and optimized them for mobile viewing.
You can find the new application here
(Might not be available until reviewed)
Let me know what you think!

Ok thanks!

I'm having trouble with question #9
for a it's just a simple normal force question with a block on an angle. So I did the usual mgcos(angle) = Fnormal and it didn't work.
for b I used Fhor - mgsin(angle) = ma, solved for the acceleration and it also didn't work.
I'm I missing something here?

I don't think anyone will be able to publish an iPhone app because it costs $99 a year to publish with apple where android has a $25 one time fee to be able to publish. I would love to make an iPhone app, but I just can't afford it. Thank you for the interest though.

sorry heres a working link: https://play.google.com/store/apps/details?id=com.rhosoft.aplusphyisics

Did you try the second link?

I now published the app for everyone so they can read the forums blog posts and downloads. Get it here https://play.google.com/store/apps/details?id=com.rhosoft.aplusphyisics

Forgot to add the google+ community link: https://plus.google.com/u/0/communities/108101849405693991382

I have recently started work on a new and improved APlusPhysics app for android that will work with the current forums.
If you would like to be an early alpha tester join the google+ community, and then download the app at https://play.google.com/apps/testing/com.rhosoft.aplusphyisics. Thanks to everyone who decides to test, if you find a bug post it on the google+ community.
Happy Testing,
Gareth

Launch time: about 1:50
Team Member Present: all
Play by Play: launch, solids exhausted decoupled, main sail burns up until low orbit, poodle used to achieve full orbit, transfer close to periapsis of orbit, retrograde burn to achieve orbit around mun, decrease orbit until on collision course, slow decent, ran out of fuel just before landing, hit at about 20 m/s engine, fuel tank and nose cone explode, rover miraculously lands wheels down intact attached to decoupler, decoupler decoupled, rover drives off.
Time of Flight: 1 day, 5 hours, 55 min, 31 seconds
Summery: sweet fast rover landed on the surface of the moon. We can now explore the surface in style and comfort. All systems are in order and running well. Might try to find the Apollo 11 landing site.
Learnings: Rovers are hard to get off of the ship you put them on, until the ship underneath it explodes. Will look into a safer way to deploy rover that involves less random explosions.
Strategies: Continue forward with our landing skills and try to figure out what to do next
Milestones: Working rover on the mun
Available Funds: Waiting on the CFO to put in the hours to get this measure, also not sure who the CFO is. Will try and find that out.
Well I found the CFO and he said we still have $149,228 in the bank.
