A block with mass m has a coefficient of kinetic friction Mk with the floor. If the block is obeying Newton's 1st law while being pushed at angle 0 (theta), show that the power needed to push it at velocity v is given by P=Mkv(mg+fsin0).© BrainMass Inc. brainmass.com November 30, 2021, 12:11 am ad1c9bdddf

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 ...
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.
