Water Flowing Out of Hole

  1. Dec 7, 2013 #1
    1. The problem statement, all variables and given/known data
    When a container full of water with a small hole in the side is at rest on a table, water flows out of the hole and follows an approximately parabolic arc before hitting the table. Suppose the same container is dropped down a mine shaft so that it is in free fall. Air resistance is negligible. As viewed by an observer standing at the bottom of the mine, the water flow:

    a) diminishes
    b) stops all together
    c) travels in a horizontal straight line
    d) curves upward
    e) curves downward

    2. Relevant equations

    Fg = mg

    3. The attempt at a solution

    I believe the answer is d), because the water in the cup will be moving down with the cup, and will only release as much water as it would if it wasn't falling. That said, water flowing down would flow up from the perspective of the observer at the bottom of the mine, right?
