Homework Help: Free Fall Problems

  1. Sep 9, 2010 #1
    1. The problem statement, all variables and given/known data
    Two balls are are released from a table top of height H = 3m at the same time. The green ball is given an initial velocity v0 = 6 m/s in the downward direction, while the red ball is given an initial velocity v0 = 6 m/s in the upward direction.
    How long does it take for the red ball to reach the floor?
    Which velocity would be greater when it hits the floor?

    2. Relevant equations

    3. The attempt at a solution

    Welcome to Physics Forums
    There are more equations for free fall motion, other than that one. Have a look at them.

    You'll want an equation that uses t, since the problem is asking for time.
