The cart on the top has two arrows to the right of it. The first arrow is assigned a value of 60 N and the second arrow is assigned a value of 30 N. Below the cart, it indicates that adding the two forces together equals 90 N to the right. The cart on the bottom shows an arrow to the left equaling 10 N and an arrow to the right equaling 30 N of force. Below the cart it indicates that adding the two forces together equals 20 N of force to the right.
