Final answer:
The final displacement of the puck is the straight-line distance between the two players, which is 10 meters. Displacement is a vector quantity and includes both magnitude and direction, but since the direction is not specified in the question, we focus on the magnitude, which is 10 meters.
Step-by-step explanation:
When Kreider passes the puck directly across the ice to Girardi, who is located 10 meters away, we can regard this as a motion along a straight line since there is no indication that the puck changes direction. Therefore, the final displacement of the puck is simply the straight-line distance between the two players, which in this case, is given as 10 meters. Displacement is a vector quantity and includes both magnitude and direction, but since the direction is not specified in the question, we focus on the magnitude, which is 10 meters.
