A 0.2 kg block is initially at rest on a rough, horizontal tabletop. A student then pulls the block across the tabletop with a constant horizontal force of 0.75 N. After being pulled a distance of 2 m, the speed of the block is 3 m/ s. The amount of energy dissipated by friction between the block and the tabletop is most nearly
