Final answer:
Devin did 200 J of work by pushing the table over a distance of 2 meters with a force of 100 N. The correct calculation is to multiply the force (100 N) by the distance (2 meters).
Step-by-step explanation:
The calculation of work done by Devin when he pushed a table can be found using the definition of work in physics, which is equal to the force applied multiplied by the distance over which the force is applied, provided the force acts in the direction of the movement. Since Devin pushed a table 2 meters using a force of 100 N in the direction of the motion, we use the formula:
Work (W) = Force (F) × Distance (d)
The correct answer is therefore C. Multiply 100 by 2.
Let's apply the formula:
W = 100 N × 2 m
W = 200 J (joules)
So, to answer the student's question directly, Devin did 200 J of work pushing the table.
