question 29

Multiple Choice

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?

• A)−3.3 J
• B)+1.3 J
• C)+3.3 J
• D)−1.3 J
• E)+4.6 J
