1. The problem statement, all variables and given/known data An object is thrown downward with an initial speed of 4 m/s from a height of 99m above the ground. At the same instant, a second object is propelled vertically from the ground level with a speed of 25 m/s. The acceleration of gravity is 9.8 m/s^2. At what height above the ground will the two objects pass each other? Answer in units of m. 2. Relevant equations http://www.glenbrook.k12.il.us/gbssci/phys/Class/1DKin/U1L6a1.gif [Broken] 3. The attempt at a solution Well I tried to find a common variable to plug in. I tried to plug in the position, then find time, then find the position, but it didnt work. Any help is appreciated.
