A 4.10 kg block of ice is placed against one end of a horizontal spring that is fixed on the other end, has
force constant k = 210 N/m and is compressed 0.025 mm. The spring is released and accelerates the block along
a horizontal surface. Ignore friction and the mass of the spring.
* Calculate the work done on the block by the spring during the motion of the block from its initial position to where the spring has returned to its uncompressed length.
