### Assignment

For the following problems use the standard x,y coordinated system. Treat north as the positive y direction and east as the positive x direction. Image a car is driving around on the streets of physics town. Your job is to measure the average speed and velocity using measured distances and measured times.

### Step 1

Calculate the distance and displacement between each step and calculate the total distance and displacement. Starting point Step 1 Time to Reach Step 1 Step 2 Time to Reach Step 2 Step 3 Time to Reach Step 1 Origin to a in 10 sec then b in 30 sec Origin to a in 5 sec then d in 20 sec Origin to b in 20 sec then d in 10 sec Origin to c in 20 sec then f in 5 sec then b in 10 sec Starting at b then g in 10 sec then h in 8 sec Origin to g in 8 sec then h in 7 sec then a in 5 sec Origin to 2 x a in 5 sec then e in 3 sec Origin to c in 20 sec then f in 8 sec then d in 3 sec

### Step two

Calculate the speed an velocity the car is moving between each step.
Calculate the average speed and average velocity for the total trip in each problem.
