When will they pass each other>

  1. Aug 2, 2005 #1
    An object is thrown downward w/ initial speed (t=0) of 10 m/s from height 60 m above the ground. At the same instant (t=0) a second object is propelled vertically upward from ground level with a speed of 40 m/s. At what height above the ground will the two objects pass each other?

    Ok ... I know the initial velocities, initial time, initial position...Im stuck, this should be really easy if I just get a big hint. I'm gonna go work on this and try to figure it out.

    Well, you know the position value will be the same, translate each situation in terms of distance.
