Ahikers total displacement is 13 km at 35 degrees north east. if the hiker wishes to return to his starting point on a trail that goes due south and then due west, what will be the total distance he travels on his return trip? draw a diagram to show the directions and distances he travels .

18.1 km

Explanation:

The problem can be solved by resolving the vector representing the displacement into its components along the north-south and east-west directions.

Look at the figure below: the displacement is the vector that connects A (starting point) to B (ending point), while the distance covered during the return trip is the sum of the length of the two components along the north-south and east-west direction.

Using vector rules, we find the magnitude of the two components:

East-west:

North-south:

So the total distance covered during the return trip is

c. convergent boundary.

explanation:

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
