This problem has really been bugging me. After several attempts, I don't even know where to start anymore.(adsbygoogle = window.adsbygoogle || []).push({});

A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof 2.00 s later. Air resistance may be ignored.

(a) If the height of the building is 60 m, what must be the initial speed of the first ball if both are to hit the ground at the same time?
