Two students are on a balcony 18.2 m above the street. One student throws a ball (ball 1) vertically downward at 15.7 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? S (b) What is the velocity of each ball as it strikes the ground? all 1 magnitude direction ball 2 magnitude Your response differs from the correct answer by more than 10%. Double check your calculations. m/s downward 8 direction downward m/s 8 (c) How far apart are the balls 0.500 s after they are thrown? m
