6. A 5 kg block is accelerated from rest by a compressed spring of spring constant 600 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 =0.20. The frictional force stops the block in distance D = 8.0m. What are: a) the increase in the thermal energy of the block-floor system? b) the maximum kinetic energy of the block? c) the original compression distance of the spring? -D (Hx) - No friction
