Problem $1[12$ pts$]$

Briefly explain why is there an upper limit on the usable frequency range for an accelerometer.

The sensitivity determined for an accelerometer is $100m\frac{V}{g}.$ I want to use the accelerometer to calibrate a load

cell with an impact hammer $($Hammer applies an impact and measures the corresponding force applied$).$

I apply an impact with the hammer to a mass $(0\mathrm{.}5kg)$ fitted with the accelerometer. The accelerometer outputs a

peak signal $($at impact$)$ of $350mV.$ The load cell reads a peak output voltage of $300mV$ at the impact. Assuming

everything is perfectly aligned, what is the sensitivity of the load cell in the impact hammer $(m\frac{V}{N})?$
