You are standing on top of a 50 meter tall building with your Physics lab partner. Each of you has a tiny stone, and you want to see which one hits the ground first. Unfortunately, your lab partner is a cheater (make a note: get a new lab partner for next semester). When you say "go", you drop your stone, but your lab partner throws the stone downwards with an initial speed of 6 m/s. Obviously, your partner's stone will hit the ground first. How much time elapses between the impact of your partner's stone and your stone?
