1. A car is driven 80 km west and then 30 km 45 degrees south of west. What is the displacement of the car from the point of origin? (magnitude and displacement)

2. A delivery truck travels 18 blocks north, 10 blocks east, and then 20 blocks south. What is the trucks final displacement from its starting point? Assume the blocks are all equal length.

Also help with: Given the following two vectors, where Vector A is 6.3 meters and Vector B is 3.5 meters: Determine the magnitude of the following vector sums:

a. A+B

b. A-B

c. B-A

I don't know where to start. Every example i looked at didn't help me solve these and they seem to contradict each other. I'm just starting in physics and deeply confused. Please help...
