Final answer:
The work done on a 2.0-kilogram object when a net force of 5.0 newtons moves it a distance of 3.0 meters is 15 joules.
Step-by-step explanation:
The question relates to the concept of work in physics, which is defined as the product of force and displacement in the direction of the force. To calculate the work done on the object by the net force, we can use the formula Work (W) = Force (F) × Distance (d). Given a net force of 5.0 newtons moving a 2.0-kilogram object a distance of 3.0 meters, the work done can be calculated by multiplying the net force by the distance:
W = F × d = 5.0 N × 3.0 m = 15 J
Therefore, the work done on the object is 15 joules.
