Leaving from a height of 0.3 m on an inclined plane, a body with a mass of 0.2 kg travels along a horizontal plane and compresses a spring arranged as shown in the figure. Disregarding friction: describe the energy transformations involved in this movement; calculate the energy gained by the spring; determine the deformation of the spring knowing that its elastic constant k = 5 N/m; justify the statement that, being a conservative system, the block will go up and down the ramp indefinitely.
