Velocity

1. 1($) 20 meters/second 
2. 2($) 20 meters/second northeast

v = d / t

is called object's displacement and defined as the _______-line distance from object's starting position to its final position, including the direction from start to finish

v = d / t

v = d / t

v is 1($)

d is 2($)

t is 3($)

1. 1($) velocity
2. 2($) speed
3. 3($) time
4. 4($) displacement

Suppose a jogger leaves her house and jogs north 300 meters to the streetlamp on the corner.  She turns west, jogs another 300 meters, and gets the oak tree 2 minutes after leaving home

1. Which of the three distances given in the figure is the displacement d? 1($)
2. What is the jogger's average velocity? 2($)
3. What is the total distance (not displacement) travelled? 3($)
4. What is the average speed (not velocity) during the 2 minutes? 4($)
