Locomotive physics question about distnce and displacement?

Question

A locomotive moved 18.0 m [W] in a time of 6.00 s and stopped. After stopping, the locomotive moved 12.0 m [E] in 10.0s.

A. Determine the distance travelled by the locomotive. Show work please and thanks.

B. Determine the displacement of the locomotive. Show show please, thank you.

Answer 1

a) you have the distance, 18+12 = 30m

b) displacement vector is 18m W, + 12m E = 6m W

.

Answer 2

a

the distance travelled is 18 + 12 = 30 m

b

the displacement is 18 - 12 = 6 m
