Final answer:
The work done on the object when a force of 5.0 newtons moves it a distance of 3.0 meters is calculated using the formula work = force × distance, resulting in 15 joules of work done. So, the best answer is c,
Step-by-step explanation:
The student asked how much work is done on a 2.0-kilogram object when a force of 5.0 newtons moves it a distance of 3.0 meters.
To find the work done on the object, we use the formula work (W) = force (F) × distance (d).
Given that the force is 5.0 newtons and the object is moved 3.0 meters, the work done is W = 5.0 N × 3.0 m = 15 N·m, which is equivalent to 15 joules since 1 joule = 1 newton-meter.
Therefore, the correct answer is C. 15.
