Your roommate accidentally tosses your Frisbee onto the roof of a 16m high building. You figure you are going to have to go looking for a ladder, but as you stare up at your favorite competition disk, you realize you could possibly knock it loose with a stone. You don't want to look like an idiot in front of your roommate however, and the well in the courtyard suddenly gives you an idea. You drop a stone into the well and note that you hear a splash 2.0s later. You repeat the experiment with another stone, but this time you throw the stone down as fast as you can. This time the splash comes 1.0s after the stone leaves your hand. Armed with this information you carry out a quick calculation. Can you use the stone, or do you need to go get a ladder?
