A man on a treadmill is walking at 1.5 m/s to the left. The treadmill is going at 2 m/s to the right. If you are standing still, it looks like the man is moving: 0.5 m/s left 3.5 m/s left stationary 0.5 m/s right 3.5 m/s right Ralph is confused about how his book defined the components of a vector.
