An egg is thrown straight down at 1.4 m/s from a tall tower. Two seconds (2 s) later, a second egg is thrown straight up at 4.0 m/s. How far apart are the two eggs 4 s after the second egg is thrown? What is the minimum separation between the eggs and when does it occur? Ignore the effects of air resistance.
