Final answer:

The work done is calculated using the formula Work = Force × Distance. Given that the force is 2 N and the distance is 4 m, the work done should be 8 J. However, this answer does not match any of the provided choices, which suggests a possible error in the units of the choices.

Step-by-step explanation:

To calculate the work done by the cat on the toy mouse, we use the formula Work (W) = Force (F) × Distance (d). The cat applies a force of 2 newtons over a distance of 4 meters. Since the force is in the direction of the motion and is constant, the work done can be calculated straightforwardly.

W = F × d = 2 N × 4 m = 8 Joules (J).

However, the given units for the answer choices seem to be in smaller increments, possibly due to a typing error. If we assume that the units were meant to be in 0.01 increments, then the correct calculation would be:

W = F × d = 2 N × 4 m = 8 J, but in the context of the given answer choices, it would be 0.08 J (since 8 J = 800 × 0.01 J).

Therefore, among the provided options, the closest is:

  • B. 0.16 J

However, this is not the correct answer given the traditional understanding of work calculation in joules. We would need to adjust the provided options to accurately reflect the correct calculation, which is 8 J, not represented in the choices.
