An accelerometer in the control system consists of a 4.60 g object sliding on a horizontal rail. A low-mass spring attaches the object to 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 0.900g, the object must be located 0.400 cm from its equilibrium position. Find the force constant required for the spring.
