"resting velocity" LOL
i think it's painfully obvious that the question is asking for velocity upon impact with the water. otherwise why would it even say it takes 10 seconds to hit the sea below? the whole question is talking about the ball hitting the sea, then it asks for a velocity.. seems open and shut to me that they want the velocity at impact. i mean do we really need to specify what reference frame we're talking about in this question, or is it just implied that we're in the frame of the earth? otherwise you could just extend ANY problem infinitely into the future and say dumb [censored] like
"well who knows what's going to happen to the ball a million years from now! also it's on the earth and the earth is spinning around and flying around the sun, so it's moving pretty fast lol!!"
