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, 5 m east, and then 5 m south.
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.

To determine which option accurately describes a scenario in which a tortoise experiences a displacement of 10 m south, we need to analyze the movement described in each option.

Option 1: A tortoise starts at a position of 3 m south. It moves 4 m east, 2 m west, and then 3 m north.
Here, the tortoise starts 3 m south and then moves in different directions, ultimately ending up 3 m north. Therefore, this option does not accurately describe a displacement of 10 m south.

Option 2: A tortoise starts at a position of 0 m. It moves 10 m west, 5 m east, and then 5 m south.
In this scenario, the tortoise starts at a position of 0 m and moves 10 m west, then 5 m east. The movement described so far does not bring the tortoise closer to a displacement of 10 m south. On moving 5 m south, the tortoise would reach the 10 m south displacement. Therefore, this scenario accurately describes a displacement of 10 m south.

Option 3: A tortoise starts at a position of 0 m. It moves 10 m west,10 m east, and then 10 m south.
Similar to option 2, the tortoise starts at a position of 0 m and moves 10 m west. However, it then moves 10 m east, effectively canceling out the displacement to 0 m again. Moving an additional 10 m south would not result in a displacement of 10 m south as the tortoise would end up back at 0 m. Therefore, this option does not accurately describe a displacement of 10 m south.

Option 4: A tortoise starts at a position of 2 m north. It moves 4 m west and then 7 m south.
Here, the tortoise starts at a position of 2 m north and moves 4 m west. This movement does not contribute to a south displacement. Then, it moves 7 m south, resulting in a displacement of 7 m south. Therefore, this option does not accurately describe a displacement of 10 m south.

Based on the analysis, option 2 accurately describes a scenario in which a tortoise experiences a displacement of 10 m south.

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

Take a look at option C After the first three moves aren't you back at the starting point? If so then what does your 4th move provide?
