Question
Two students are on a balcony 18.5m above the street. One student throws a ball vertically downward at 13.7m/s; at 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 velocity of the first ball, the second ball as itstrikes the ground answer in m/s, the difference in the time the balls spend in the air, answer in units of s and how far apart are the balls 0.434s after they are thrown? Answer in units of m
Explanation / Answer
I'll assume the student throwing the ball upward is also throwing it at 13.7 m/s
disregarding air resistance the ball being thrown upward would take exactly twice as much time as the ball being dropped
