A soccer player kicks a ball, applying a force of 1,000 newtons over a distance of 0.2 meter. The ball travels 50 meters down the field before another player stops the ball. How much work was done during the kick?(1 point)

The work done during the kick can be calculated using the formula: work = force x distance. Plugging in the given values, we get:
work = 1000 newtons x 0.2 meters = 200 joules
Therefore, the correct answer is 200 joules.

To calculate the work done, we use the formula: work = force x distance. In this case, the force is equal to the weight of the box, which is 50 newtons, and the distance is 0.5 meters.
work = 50 newtons x 0.5 meters = 25 joules
Therefore, the correct answer is 25 joules.
A person gets a running start toward a wall from 5 meters away. The person pushes the wall with a force of 500 newtons, but the wall does not move. How much work is done by the person?(1 point)

In this scenario, since the wall does not move, no work is done. Work is defined as the force applied to move an object over a certain distance. In this case, although the person exerts a force of 500 newtons, the wall does not move. Therefore, the correct answer is 0 joules.
