In a control system, an accelerometer consists of a 4.70-g object sliding on a calibrated 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 0.800g, the object should be at a location 0.500 cm away from its equilibrium position. find the force constant of the spring required for the calibration to be correct.
