what's with the answer to that "final velocity" question?


it seemed kind of like a trick question, final velocity should be zero right, since it comes to a stop after being dropped? i can't remember the wording but i remember thinking 100 m/s or 0 could be the answer depending on interpretation.

Also, "This type of rock is buried deep within the earth's crust" couldn't that question be legitimately answered igneous or metamorphic?

it said what is the velocity as it hits the water, right? there's nothing tricky about that question.

The funny thing, is that this is how Daryn read the question.. I think we all agreee that this is how the question should have been worded to remove any ambiguity, and TEST the matter at hand. Instead some, myself included thought perhaps it was a trick question. I don't disagree that my answer was wrong, but I wouldn't have gotten the question wrong if it was phrased the way Daryn wrote it.
