1. Two soccer players kick a soccer ball back and forth along a straight line. The first player kicks the ball 12 m to the right to the second player. The second player kicks the ball to the left weakly; it only moves 2.3 m before stopping. (Consider the right to be the positive direction. Where applicable, indicate the direction with the sign of your answer.)

(a) What is the total distance that the ball moved? (m) (b) At the end, what is the displacement of the ball (from the first player)? (m)

2. A truck travels due east for a distance of 1.5 km, turns around and goes due west for 9.8 km, and finally turns around again and travels 3.5 km due east.

(a) What is the total distance that the truck travels? (km) (b) What are the magnitude (m) and direction (east, west, or neither) of the truck's displacement?
