Question

A truck moves 20.0 km north, then 30.0 km in the direction 30o east of north, and then 40.0 km west. Determine the following:

A. Total distance traveled by the truck

B. Displacement vector of the truck

C. Magnitude of displacement of the truck

*Use the hint

*I need a solution

*There's a picture where your final answer should be the same as shown

then 40.0 km west. Determine the following:
A. Total distance traveled by the truck
B. Displacement vector of the truck
C. Magnitude of the displacement of the truck
Hint: Use the unit vectors î and î to denote the unit vectors pointing to the East and to
the North, respectively.

Magnitude of the displacement of the truck Hint: Use the unit vectors î and î to denote the unit vectors pointing to the East and to the North, respectively.
3A. The total distance traveled by the truck is 90.0 km
3B. The displacement vector of the truck is 7 = -25.0 km î + 46.0 km j or,
equivalently 25.0 km West and 46.0 km North.
3C. The magnitude of the displacement of the truck is 52.4 km
