    Somewhere in the universe live a peaceful race of things called quarks.

    They live on the planet of the quarks.

    These super intelligent little creatures were created through an unknown phenomena.

    These quarks currently live on what many Americans would call a football.

    Over the planets existence it has deflated to the minimum weight allowed by the NFL.

    These quarks have constructed an amazing spacecraft made out of the "pig skin."

    The spacecraft weighs 10000 times greater than the average quark.

    The average quark is physically identical to its distant cousin here on earth.

    What is the approximate escape velocity of this spacecraft manned by a crew of 19 quarks?

    Would the location on the planet of the quarks chosen as the designated take off position matter?

    What if the football was filled with mercury and the deflated football weighed 10 ounces?

    Use theoretical values for any unknowns.

    These demands are wildly incompatible. Since 10000 of even the heaviest quark (the top quark) are the tiniest fraction of a gramme, the NFL players would have to be kicking vacuums for this to work.

    Yes, the distance to the centre of gravity varies and with that the gravitational force.

    Richard,

    I don't understand what NFL players have to do with the planet of the quarks.

    It is my understanding that if it can be measured, it can be figured.

    I really thought this was going to be a simple problem.

    I think I may have made a mistake however:

    Is it possible to figure the mass of an NFL football filled with mercury without actually conducting the experiment?

    I don't think it is, and I doubt anyone here will go out of their way to weigh it.

    Perhaps it is possible to find the mass with the given estimate (probably not even close) of the deflated football versus one filled to standards.

    Here is a completely different question.

    Why will an aircraft climb more quickly then descend?

    I don't understand the question. I am however aware that sometimes a climb is faster when preceded by a dive. I don't know why.

    Possibly because when climbing you are going into less dense air and when during decent you are going into denser air and thus more drag.

    You specified that this spaceship weighed as much as an NFL football. You also specified that it weighed as much as 10000 quarks. Those two demands are incompatible. It's as simple as that: 10000 of even the heaviest quarks weigh a minute, immeasurably minute fraction of even the most deflated NFL football.

    No, the planet weighs as much as a football, the spaceship the quarks built on its surface weighs as much as 10,000 quarks.
