Final answer:
The chair moves a distance of 3.9 meters when a force of 320 N does 1248 J of work on it.
Step-by-step explanation:
The student has asked about the work done by a force in moving an object a certain distance. Work, in physics, is defined as the product of the force applied to an object in the direction of its displacement and the distance it moves. To solve the problem given, the work done formula (Work = Force × Distance) can be used to calculate the distance the chair has moved.
Since we know the amount of work done (1248 J) and the force applied (320 N), we can rearrange the formula to solve for the distance (Distance = Work / Force).
To calculate the distance, divide the work (1248 J) by the force (320 N):
Distance = 1248 J / 320 N = 3.9 meters.
The chair moves a distance of 3.9 meters as a result of the 320 N force exerting 1248 J of work on it.
