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
    v^2=v0^2+2a(x-x0)


    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.
