Two students are on a balcony 19.6 m above the street. One student throws a ball vertically downward at 14.7 m/s. Att the same instant, the other student throws a ball vertically upward at the same speed. The second ball just misses the balcony on the way down. What is the difference in the time the balls spend in the air? What is the velocity of each ball as it strikes the ground? How far apart are the balls 0.800 s after they are thrown?
I don't even know where to start on this one. Thanks for your time!!
