An accelerometer in a control system consists of a 3.65-g object sliding on a horizontal rail. A low-mass spring is connected between the object and a flange at one end of the rail. Grease on the rail makes static friction negligible, but rapidly damps out vibrations of the sliding object. When subject to a steady acceleration of 0.500-g, the object must be located 0.350-cm from its equilibrium position. Find the force constant required for the spring.
