Question

Calculate the total displacement of a mouse walking along a ruler, if it begins at the location x = 5 m, and then does the following:

- It walks to x = 12 m
- It then walks a displacement of -8 m (NOT the same as x = -8 m)
- Lastly, it walks to the location x = 7 m​

Answer 1

18

Step-by-step explanation:

12 - 5 + 8 = 15

12 - 8 = 4

7 - 4 = 3

15 + 3 = 18
