In the figure, a 3,9 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 kinetic friction uk = 0.276. The frictional force stops the block in distance D = 7.4 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 (a) Number i Units (b) Number i Units (c) Number i UnitsStep-by-step explanation
