[AI-generated answer — Bot GPT 3.5]

To calculate the work done, we need to use the formula work = force x distance. The force applied is 98 Newtons, and the distance over which the force is applied is 4 meters. However, we need to consider that the box is lifted a distance of 2 meters, so we will use that distance instead.

Work = force x distance
Work = 98 N x 2 m
Work = 196 Joules

Therefore, the correct answer is 196 Joules.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To find the amount of work done by the person using the lever, we need to use the formula:

Work = Force × Distance

The force applied is 98 Newtons and the distance over which the force is applied is 4 meters. Therefore, the work done is:

Work = 98 N × 4 m = 392 Joules

So, the correct answer is:

392 Joules

To find the amount of work done, we can use the formula:

Work = Force × Distance

In this case, the force applied is 98 Newtons and the distance is 2 meters. So the work done is:

Work = 98 N × 2 m = 196 Joules

Therefore, the correct answer is 196 Joules.
