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?
