A spring that is hung from the ceiling stretches 0.495 m when a 0.188 kg mass is hung from it. the spring is taken down and laid horizontal on a table and attached by its free end to a rigid wall. with the same mass attached, the spring is then compressed by 0.695 m from its rest length and released. determine the maximum velocity of the mass in this horizontal configuration.
