I dropped a 2 kg brick from the balcony of an apartment, 30 m above the ground. At a time of 1.00 s after the 2 kg brick is dropped, my brother throws a second 2 kg brick vertically downward from the balcony one storey below, 27.5 m above the ground. The initial velocity of the second brick is 12.0 m/s [down].

How far above the ground are the two objects when they meet? (assume no air resistance)
