During the filming of a motion picture, a Hollywood stuntman is driving a motorcycle on top of a train jumping from car to car while the train is moving. A helicopter with a movie camera is flying nearby in order to film the action. The helicopter is flying west at 33.2 m/s relative to the ground. The train is moving east at 10.6 m/s. If the motorcycle is moving east at 11.7 m/s relative to the train, what is the velocity of the helicopter relative to the motorcycle in meters per second?
