In the figure, a 3.0 kg block is accelerated from rest by a compressed spring of spring constant 620 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction /k = 0.289. The frictional force stops the block in distance D = 7.8 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? No friction D (HX ) (a) Number i Units V (b) Number Units v (c) Number Units V
