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.
