Ball and chain- (kidding, no chain)

  1. Sep 12, 2009 #1
    If one ball is dropped and another is thrown down from the same height, which will arrive at the ground first? Won't they get there at the same time?

    It depends on the initial height where the balls are dropped and thrown and the velocity (speed & direction) of the ball thrown downward. If you meant throwing the ball in the direction perpendicular to the horizontal ground, you can calculate how fast you should throw the ball downard by using some simple mechanics formulae.

    This sounds like the same question you asked about balls being dropped or thrown down from a plane. You should be able to anser it yourself by now!
