In the figure, a 2.7 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 Hk = 0.205. The frictional force stops the block in distance D = 8.3 m. What is the original compression distance of the spring? No friction D (H)
