  8. Launch Report and Debrief

     

    Launch Time: 13:24, 5/19/14

    Team Members Present: Tim Walsh

    Play-by-Play: Half throttle off launch pad, accelerate to 200 m/s.  Decrease throttle to keep below 200m/s until at 6km.  From there go full throttle.  After fuel runs out, separate fuel tank from pod and parachute.  When pod is 400m from ground, deploy parachute.  After soft landing, recover vessel.

    Photographs: Photos to follow

    Time-of-Flight: Didn’t track, but ~00:03:00

    Summary: Not many risks here, all in all a good flight.  Keep it simple, stupid!

    Opportunities / Learnings: Simple is nice, keep it manageable.

    Strategies / Project Timeline: Let’s move on!! Going to go grab that 50km milestone!

  10. Does anybody have any great ideas for how to do parts b-d?  It seems like there should be a way to integrate the force of the spring, subtract the force of friction, do some math-o-magic, and pop out an answer.  Or maybe look at the Uspring and work (hehe, puns) from there?  It's (obviously) the fact that friction is non-conservative that makes the whole thing tough.

     

    Also- Kerbal Space Program makes doing homework really hard...

  11. break it up into x components and y components.  You know that Vox and Vfx are equal and Ax is zero, and that Ty equals Tx (times are the same..duh).  You also know that Vox=Voy because the angle is 45deg.  Do some kinemagic equation stuff and find x=.5(Vo+Vf)T, which becomes 618=Vx(T) for the x component and y=VoyT+.5aT^2, which becomes -3=Vx(T)-16T^2 for the y components.  (Vx is interchangeable for Vox, Vfx, and Voy because they're all the same.  Doe some systems magic and you'll get your answer (140.287 f/s, I hope).

  12. So for 16 on the WebAssign due tonight, I feel like I'm completely missing something.  I algebra-ized two of the kinematics equations [ x=.5(vf+vo)t and vf=vo+at ] and got x=.5(2vo+at)t, hoping that then I could set the two rocks equal to each other because their x values are the same, and then solve for time somehow.  This failed. Miserably.  I looked a little bit at trying to set x=vot+.5at^2 equal to itself, again because the two x values should be the same, but didn't get anywhere.  It feels like you have to make an equation equal to t, and then figure out a way to set that equal to itself (with one side adding the extra time until the second rock is thrown).

     

    Hope this makes some semblance of sense... any suggestions?
