Question: A block slides on a rough, horizontal surface from point A to point B. A force (magnitude P = 3.2 N) acts on the block

A block slides on a rough, horizontal surface from point A to point B. A force (magnitude P= 3.2 N) acts on the block between A and B, as shown. Points A and B are 1.5 m apart. If the kinetic energies of the block at A and B are 5.0 J and 7.0 J, respectively, how much work is done on the block by the force of friction as the block moves from A to B?
