Two students are on a balcony 24.3m above the street. One student throws a ball, B1, vertically downward at 12.5 m/s. At the same instant, the other student throws a ball, B2, vertically upward at the same speed. The second ball just misses the balcony on the way down.
A.) What is the difference in time the balls spend in the air?
B.) What is the velocity of each individual ball as it strikes the ground?
C.) How far apart are the balls 0.470s after they are thrown?
