  7. I'm helping my kid with a question on a test and I can't figure this one out. I already have the answer, but can someone explain how to solve it?

    A 0.24-kilogram glider moving with a velocity of 0.6 m/s collides with and sticks to a 0.26-kilogram glider moving with a velocity of 0.2 m/s. The final velocity v of the two gliders is

    A. 0.392 m/s.
    B. 0.184 m/s.
    C. 0.092 m/s.
    D. -0.092 m/s.

    Thanks,

    Jon

    You may well be, but for me you're missing some essential attributes:P




    Hey Zep...I'm pretty sure the Bastard has a penis...you should be good to go:o

    ...sorry, you made that too easy:P

    pilot chute which was in a pouch in the small of the back



    Interesting. On the rig I have, the leg throw out looks original. However, there's still a slot between the padded part of the backpad, and the actual container & webbing, at the lower right, small of the back. So it creates a pouch between the two layers. I don't know why it is there, but it would be perfect for keeping a stash bag if doing a demo or landing off.
    Hi pch,
    The "Slot" you refer to was the original pilotchute stow pouch. The pullout lanyard came out and down to a piece of velcro on the side of the bellyband. Originally the pullout lanyard was attached to the bottom of the pilotchute , then later to the top.


    Here is what happened to me using that deployment system :o. To this day, I still think of the ugly mess I would have been in if I decided to do the loops instead of pulling[:/]

  13. This is gonna sound kinda dumb...but I thought the thread title was for a Hamilton Beach Demo - like a new coffee pot:P

    If you add "Jump" to the end of the title it might get some responses...juz sayin;)

    edit misspelled "beech"

    (Please state why.)

    What if a third-party, in the interest of skydiver safety, employed a "myster skydiver". I.e. a tandem passenger, AFF-student or otherwise that was actually D-licensed, credible and knowledgeable about proper procedure to show up at random DZs and report back on his or her findings?



    I said yes...but (there is always a butt) how does one make sure the plant isn't bias. Maybe I should have said no because of the political nature of a test like this? ....hummmmm...[scratching head - may be reconsidering]...

  16. I understand everything you said, and anticipated such responses...that's why I said "YMMV". If you ever find yourself with a discomfort like a kidney stone, it is a pain reliever that will do just that, relieve pain...it is that good. Burns all over your body, it prolly won't help so much...but as a strong pain reliever it's very good. House is an addict and I said that as a point of humor...humor...k?

    What can I say I'm bored and feeling a little goofy. Its the vicodin. What's it do for you? Haven't taken vicodin or maybe you've been on a different pain killer? Then please share!



    For me...a wonderful pain reliever. Add a little alcohol and it's the perfect pain reliever. I can't sleep on vicodin...but that's ok, it takes the pain away - I'm talking kidney stone level pain! YMMV, but if it works for House, who the hell am I to challenge his conclusions?

    What is your lession, smart guy?



    Are you asking what "is" my lesson, or what "was" my lesson? I'll answer both;)

    :D:D:D

    What "was" the lesson:

    I bought a brand new, state of the art, Jonathan 136 when they first came out and I front risered myself, pretty much, right into the dirt...nothing broken. I'd made 50 jumps, or so, on the canopy at the time. A dozen of those were using the exact same approach. At that point, I decided I just may not have everything it takes to continue attempting these kind of landings - my ego was crushed, NOT. It all happened in the blink of a eye ;) I had over 500 jumps, was a static line J/M I, and jumped and taught class every weekend at the time.

    What "is" the lesson:

    Prior to everyone having internet access, news of incidents moved rather slowly across the country. We now have up to the minute reports of incidents on this site, and some of the best people in skydiving posting here. And people still don't get it.

    A wealth of knowlege, experiance, and history are at your fingertips...all you have to do is listen.

    When almost half of the fatalities are a result of improper canopy flight, and a huge percent are high-performance canopy related, it indicates that not all pilots should be under the canopy the're flying. People aren't listening to what the're are hearing because they don't want to know that something bad can happen to them.

    Same old story.

    Again I'll ask:
    What is so hard to understand about this?

    Looks like it have two AIM-9 Lima missiles at station 1 and 9, and two GBU-10 bombs at station 3 and 7.



    Are you sure it's not a BFG 9000 Nutbuster at Station 13:P

    Nice pic OP;)

  25. I've never really cared for the Ferrari vs Taurus anaology because of what you said about them both being able to be driven slowly - and that is how people think.

    The problem is, human nature dictates that they will only drive the Farrari slow for a week or two. There is no question that the Ferrari will be squealing tires in very short order, long before the driver realises what it takes to handle the car properly...wringing it out so to speak.

    Once the driver "gets away with it" for a while, he will try something that results in the Ferrari and a tree, trying to share the same space at the same time. The Ferrari will crush and bend absorbing most of the impact and the driver, for the most part will walk away.

    I believe that most people will be extremely careful under their new small canopy for many jumps, just to keep us from talking about them in the incident forum, but sooner or later, they're going to start wringing it out, make a mistake or do an avoidance turn improperly and, faster than they can "shi", they're on the ground with bones sticking out. Unlike being in a car, there is nothing between the pilot and the ground.

    Swooping and high performance canopy flight can't be done sucessfully for 100s or 1000s of jumps by just anyone - not only does it require an extreme amount of dedication, practice, and experiance...it also requires exceptional vision, depth perseption, quick reflex muscle reflex and a "feel" of canopy flight that only a few people have.

    When folks can put their ego aside and finally understand that simple fact, our fatalities will start to decline.
