Un collarín liso C, de 2 Kg, se ajusta con holgura en el pistón vertical. Si el resorte no está estirado cuando el collarín está en la posición 1, determine la rapidez con la que el collarín se encuentra en la posición 2 (y = 1 m), si (a) se suelta desde el reposo en 1 y (b) se suelta en 1 con una velocidad hacia arriba de 2 m/s. (Resuelva mediante el Principio de conservación de la energía).
