Amass is suspended on a vertical spring. initially, the mass is in equilibrium. then, it is pulled downward and released. the mass then moves up and down between the "top" and the "bottom" positions. by definition, the period of such motion is the time interval it takes the mass to move: mark all the correct statements among those provided below. view available hint(s) mark all the correct statements among those provided below. from the top position to the bottom. from the equilibrium position to the bottom. from the bottom position to the top. from the equilibrium position to the bottom and then back to the equilibrium. from the equilibrium position to the top and then back to the equilibrium. from the equilibrium position to the top. from the top position to the bottom and then back to the top. from the bottom position to the top and then back to the bottom.
