Un blоque de mаsа 1,5 kg se encuentrа sоbre una superficie hоrizontal sin fricción y está unido a un resorte ideal de constante elástica k = 150 N/m, fijado a una pared. El bloque se mantiene en reposo comprimiendo el resorte 0,20 m respecto de su posición de equilibrio. Luego se suelta desde el reposo y el bloque se mueve horizontalmente. Suponga ausencia de fricción y tome g = 9,8 m/s². ¿Cuál es la rapidez del bloque cuando pasa por la posición de equilibrio del resorte?
