Picture yourself in the castle of Helm’s Deep from the Lord of the Rings. You are on top of the castle wall and are dropping rocks on assorted monsters that are 16.15 m below you. Just when you release a rock, an archer located exactly below you shoots an arrow straight up toward you with an initial velocity of 47.9 m/s. The arrow hits the rock in midair. How long after you release the rock does this happen?
