On a hot day in summer, your friends decide to go rafting down a local river. Since you are afraid of water, your job is to provide them with refreshments from a bridge as they pass. When the first raft is 10 meters away, traveling at 3.5 m/s, you drop a can of soda, which lands right in the middle of the raft−a bull’s eye! How high is the bridge?
