Two students are on a balcony 20.5 m above the street. One student throws a ball (ball 1) vertically downward at 11.1 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?
Your response differs from the correct answer by more than 10%. Double check your calculations. s
(b) What is the velocity of each ball as it strikes the ground?
ball 1 magnitude m/s
direction
ball 2 magnitude
Your response differs from the correct answer by more than 10%. Double check your calculations. m/s
direction
(c) How far apart are the balls 0.600 s after they are thrown?
m
