The total displacement of the forest ranger's two trips would be the difference between the two distances, as they are in opposite directions. In this case, the total displacement would be 3 km south (15 km - 12 km = 3 km).
2 m south
The total displacement of the dog from the starting point can be calculated by finding the net displacement, which is the difference between the distances moved in each direction. In this case, the net displacement would be 6m north - 4m south, resulting in a total displacement of 2m north.
2 km south
The total displacement is 2km north, as the southward and northward displacements cancel each other out.
Sarah's total displacement can be found using the Pythagorean theorem. The horizontal displacement is 20 yards east, and the vertical displacement is 50 yards north minus 50 yards south, which equals 0. This means her total displacement is the square root of (20^2 + 0^2) = 20 yards.
zero
To find velocity, we need to calculate the total displacement and divide by the total time taken. April's total displacement is 30 meters north (50 m - 20 m south). Velocity is calculated as displacement/time, so her velocity is 0.5 m/s (30 m / 60 s).

The total displacement is 30 meters South. Displacement is the difference between the initial and final positions of an object, irrespective of the path taken. In this case, the person returns partially to the initial position after moving North by 50 meters.
The car has traveled a total distance of 18 miles (10 miles south + 8 miles north), but its displacement is 2 miles south. Displacement is the shortest distance between the starting and ending points, regardless of the actual path taken.
