ive been having difficulty with this problem also:(adsbygoogle = window.adsbygoogle || []).push({});

A ball is thrown downward with an initial speed of 25m/s from the top of a 210 m tall building. At the same time, another ball is thrown upward from ground level with a speed of 25m/s. At what distance from the bottom of the two balls pass each other?

the answer is supposed to be "-10 m so it is illogical."

so far i know that for the first ball Vi=25m/s d=210m a=9.8m/s^2

2nd ball Vi=25n/s d=? a=-9.8m/s^2

are we supposed to set the distance of each of the balls equal?? i really have no idea how to do this
