Physics I. Unit : potential energy and conservation of energy. A,B,C, please

In the figure, a 3.9 kg block is accelerated from rest by a compressed spring of spring constant 630 N/m. The block leaves the spring at the springs relaxed length and ther travels over a horizontal floor with a coefficient of kinetic friction uk 0.215. The frictional force stops the block in distance D 7.7 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.
