Homework Statement
A truck travels 3.45 km north and then makes a 90° left turn and drives another 4.10 km. The whole trip takes 4.50 min.
1)With respect to a two-dimensional coordinate system on the surface of Earth such that the y-axis points north, what is the net displacement vector of the truck for this trip?
2) What is the magnitude of the average velocity for this trip?
The Attempt at a Solution
1) -4.10 i + 3.45j ? Is this right?2) how will i solve for the magnitude? I mean i know we have to use the distance formula but it didn't work.
If some can explain and show some work in order for me to understand. It will be appreciated
