Question

Find the distance traveled by a boy if he walks 3 km north and then turns and walks 1 km to the west.

Include both magnitude and direction.

Answer 1

Step-by-step explanation:

Distance = total length traveled = 3 + 1 = 4 km

Displacement² = 3² + 1² = 10

Displacement = √10 = 3.16

direction = tan⁻¹(3/-1) = 71.6⁰ north of west
