HOW TO SOLVE…????

“A ball is thrown upward from the ground with an initial speed of 25 ms-1. At the same instant, another ball is dropped  from  a 15m building. When will the two balls be at the same height from the ground..???”

Anybody can help me to solve this question.. I’m try to do it but still can’t found the answer..  My head is pain! (is that correct..??) Physics, Chemistry, Computer science, Mathematics! All subjects make me crazy.. By the way, I must achieve my target! GOOD LUCK TO MYSELF!! J
