Question

a dog walks 14 meters to the east and then 20 meters back to the west.
for this motion, what is the distance moved?
distance (m) =
what is the magnitude and direction of the displacement?
magnitude (m) =
dirn =

Explanation:

Step1: Calculate the distance

Distance is the total path length. The dog walks 14 meters east and 20 meters west.
$$14 + 20$$

Step2: Calculate the displacement

Displacement is the net change in position. Let east be positive and west be negative.
$$14+( - 20)$$

Answer:

Distance (m) = 34
Magnitude (m) = 6
Dir'n = West
