Complete question :
1. A crazy dog runs 300 meters east, changes his mind and then runs 200 meters west. He then changes his mind again and runs 500 meters east. This entire trip takes 2 minutes.
a) What is the total distance traveled?
b) What is the total displacement?
c) What was the dog’s average speed?
d) What was the dog’s average velocity?
Answer:
1000 m ; 600 m east ; 8.333 m/s ` 5 m/s
Explanation:
Total distance :
(300 + 200 + 500) m = 1000 m
Total Displacement :
300 m east - 200 m west + 500 m east
100 m east + 500 m east
= 600 m east
Average speed :
Distance / time
100 m / 2 * 60 s
100 m / 120 s
= 8.333 m/s
Average velocity :
Displacement / time
600 m / 2 * 60 s
600 m / 120 s
= 5 m/s
