From Newton's first law that and object will continue moving with a constant velocity unless acted upon by a constant force.

In this case, the forces acting on the block are ...

#### Solution Summary

Applying Newton;s first law allows us to express the various forces in the system to the power consumed to move the mass. The solution contains 2 pages with diagrams and full derivations.
