Question: 0 a student pushes on a box initially at rest...

Question details

0. A student pushes on a box, initially at rest on a smooth surface. She exerts a constant force of 40 N on the box, and it moves a distance of 5 m in the direction of the force.

a) How much work was done by the student on the box?  

b) As a result of the work done by the student, the box gains kinetic energy. Explain how much kinetic energy the box will have after moving 5 m. 

c) Describe how the Law of Conservation of Energy applies to the student and the box. In your answer, please ensure you demonstrate that you understand the Law of Conservation of Energy.
