I've been working on this one problem for a while and I don't really seem to understand it. If you could help me understand how to do this, I would be much obliged. Two students are on a balcony 19.6 m about the street. One student throws a ball vertically downward at 14.7 m/s. At the same instant, the other student throws a ball vertically upward at the same speed. The socond ball just misses the balcony on the way down. a. What is the difference in the time the balls spend in the air? b. What is the velocity of each ball as it strikes the ground? c. How far apart ar the balls 0.800 s after they are thrown? I attempted the first one and got it right (by a miracle in my opinion)- 3.0 Seconds But I seem to be stuck when it comes to b.
