A simple instrument for measuring the acceleration ofgravity employs a linear spring from which a mass is suspended.At a location on earth where the acceleration of gravityis 32.174 ft/s2, the spring extends 0.291 in. If the spring extends0.116 in. when the instrument is on Mars, what is the Martianacceleration of gravity? How much would the spring extendon the moon, where g 5.471 ft/s2?
