Problem B: Airdrop (3 points) Note: These alphabet problems are additional problems for SPhL (Junior) teams only. In contrast, numbered problems are for both SPhL (Junior) and SPhL (Senior) teams. Two identical crates are each loaded with different masses and sealed. When the loaded crates are dropped separately from positions high above the ground, the heavier crate reaches terminal velocity U = 8.0 m s-', while the lighter crate reaches terminal velocity u = 2.0 m s-1. The two crates are now joined together by a light rope and, with the heavier crate dangling by the rope below the lighter one, are dropped once more from a position high above the ground. What is the new terminal velocity of the joined crates? Assume the air drag to be linear, and the length of the rope to be much greater than the size of the crates. Leave your answer to 2 significant figures in units of m s-1
