A ball is thrown upward from the ground with an initial speed of 23.2 m/s; at the same instant, a ball is dropped from a building 16.1 m high. After how long will the balls be at the same height?

thanks...

Find a formula for the height of the second ball; call that h_2(t).

Then what can you do with the two height formulas to find out when the two balls are at the same height?
