The diagram above shows three carts that can move from left to right (but not up and down or toward and away from you). The teal cart is on the left, the yellow cart is in the middle, and the pink cart is on the right. There are passengers on each cart (they are not shown in the diagram). In the reference frame of a passenger on the yellow cart, the pink cart is moving to the right with a speed 3.1 m/s. In the reference frame of a passenger on the teal cart, the yellow cart is moving to the left with a speed 1.6 m/s. A person standing stationary in the lab sees the teal cart moving to the left with a speed 3.1 m/s. From the standpoint of a person standing in the lab, what is the velocity of the pink cart? For purposes of your answer, a velocity to the right is positive and a velocity to the left is negative. The sign of your answer, positive or negative, is important.
