Question

Which option accurately describes a scenario in which a tortoise experiences a displacement of 10 m south? A tortoise starts at a position of 3 m south. It moves 4 m east, 2 m west, and then 3 m north. A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south. A tortoise starts at a position of 2 m north. It moves 4 m west and then 7 m south. A tortoise starts at a position of 0 m. It moves 10 m west, 5 m east, and then 5 m south.

Answer 1

1) A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

Explanation:

Answer 2

A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

Explanation:

Let's assume southern and eastern movement as positive and northern and western movement as negative. Since we want the displacement, starting position should not be considered.

1-) A tortoise starts at a position of 3 m south. It moves 4 m east, 2 m west, and then 3 m north.

S = -3m

E = 4 - 2 =2m

2-) A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.

S= 10m

E= 10 - 10 = 0m

3-) A tortoise starts at a position of 2 m north. It moves 4 m west and then 7 m south.

S= 7m

E= -4m

4-) A tortoise starts at a position of 0 m. It moves 10 m west, 5 m east, and then 5 m south.

S= 5m

E= 5 - 10 = -5m

Analyzing all of the previous scenarios, only one presents a 10 m southern displacement, and that is when the tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.
