A ball is thrown upwards from the top of a 50 m high building with an initial velocity of 20 m/s. At the same instant, another ball is thrown upwards with an initial velocity of 30 m/s from the ground. Determine (i) when and where they will meet each other, and (ii) the velocity of each ball at that instant.
