Physics Question:

In a control system, an accelerometer consists of a 4.35-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 0.840g, the object should be at a location 0.520 cm away from its equilibrium position. Find the force constant of the spring required for the calibration to be correct.
N/m

Explanation / Answer

ma=kx

4.35x10-3* 0.840g=k*0.52 x10-2

k=6.89 N/m
