A hiker walks 2.00 km north and then 3.00 km east, all in

2.50 hours. Calculate the magnitude and direction of the

hiker’s (a) displacement (in km) and (b) average velocity (in

km/h) during those 2.50 hours. (c) What was her average

speed during the same time interval?

Step 1

Take the north direction to be +y direction and east direction to be +x direction.

Step 2

Substituting the...
