Question
In the figure, a 2.8 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 -0.241. The frictional force
stops the block in distance D-8.2 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
