Suppose you and a friend are test driving a new car. You drive out of the car dealership and go 10 miles east and then 8 miles south. Then your friend drives 8 miles west, and 6 miles north. If you had the dealer's homing pigeon in the car. How far do you think it would have to fly to get back to the dealership? Use the simulation to test ideas. The distance that the bird has to fly represents the sum of the 4 displacement vectors. Use the simulation to test ideas you have about vector addition. After your tests, describe how you can use the simulation to add vectors.
