HELP PLEASE !! During the filming of a motion picture, a stuntman is driving a motorcycle on top of a train while the train is moving. The train is moving east at 11.3 m/s relative to the ground. If the motorcycle is moving west at 17.3 m/s relative to the train, what is the velocity of the motorcycle relative to the ground? Assume east is positive.

Hint: Use vector addition and draw a picture!
