Impact pressure (enough info?)

  1. Oct 14, 2004 #1
    Hi, I need help solving this problem. On one hand, I think that there's not enough information to solve it, on the other hand, I think there has to be a way to cancel out all the information that's not provided, and do the problem with only what's given. But I can't come up with a way to solve it. Conservation of momentum has too many unknown variables.

    "Orbiting space junk hits a spacecraft at low-earth orbital speed of 25,000 mph. Estimate the impact pressure. Also, what will happen if the spacecraft's material's yeild strength is lower than this impact pressure?"

    Given the use of the word 'estimate' in part one, I would guess that you're expected to use arbitrary values for your unknowns, based upon common sense.

    As for part two, well, no calculation is needed...

    Yeah, that's what I ended up doing.
