A block slides on a rough horizontal surface from point A to point B. A force (magnitude P → = 2 . 0 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 4 . 0 J , respectively, how much work is done on the block by the force of friction as the block moves from A to B? t3_q3_phys2425.v01.docx
