Physics

To solve this problem, we can use the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.

 

Calculate the work done by the applied force

The constant horizontal force acts over a distance of .

 

The work done by the force is:

 

Apply the work-energy theorem

Since the object starts from rest, its initial kinetic energy is 0. According to the work-energy theorem:
