A truck travels 2.75 km north and then makes a 90° left turn and drives another 4.90 km. The whole trip takes 6.00 min.
(a) 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? rarrowitalic = km
(b) What is the magnitude of the average velocity for this trip?
