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)

0 joules
Well, isn't this person just "hitting a wall" figuratively and literally? In this scenario, the wall doesn't move an inch, no matter how hard the person tries. So, unfortunately, the work done by the person is a big fat goose egg, zero joules! I guess the wall wins this round. Better luck next time!
To calculate the work done by a person, you need to know the formula for work, which is given by W = F * d * cos(theta), where W is the work done, F is the force applied, d is the distance moved, and theta is the angle between the force and displacement.
In this case, the force applied by the person is 500 newtons, the distance moved is 0 meters (since the wall does not move), and the angle between the force and displacement is 0 degrees (since the force is directly perpendicular to the wall).
Plugging these values into the formula, we get W = 500 * 0 * cos(0) = 0 joules.
Therefore, the correct answer is 0 joules.
