In the figure, a 2.6 kg block is accelerated from rest by a compressed spring of spring constant 660 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinatic friction -0.272. The frictional force stops the block in distance D-7.9 m. What are (a) the increase in the thermal energy of the block-floor system, (b) the maximum kinetic energy of the block, and (c) the original compression distance of the spring? BOTSWITH No friction - + (4₂)
