You are standing stationary along the side of the railroad tracks. A toy cannon shoots a baseball at 9 m/s. The cannon is mounted facing forward on the handlebars of a bike. Your friend is riding the bike from the front toward the back of a train car at 5 m/s. The train is traveling forward at 14 m/s. If the cannon fires at the moment the train passes, how fast is the baseball moving relative to your position?
