Answer:
The total distance of the truck is 14.6 km
The magnitude and direction of truck's disaplacement is 4 km east
Explanation:
Distance is the total path covered by the trcuk regardless of the direction since distance is described by magnitude only.
The total distance traveled by the truck is given by;
Total Distance = 1.9 km + 9.3 km + 3.4 km
Total Distance = 14.6 km
Displacement is the change in postion at a time interval. In dispalcement direction is considered.
let eastward motion be positive
let westward motion be negative
Displacement = 1.9km east - 9.3 km west + 3.4 km east
Displacement = -4 km east
Therefore, the magnitude and direction of dispalcement = 4 km east
