For a second order instrument with sensitivity of 0.35 V/(m/s2), ao 10.5 F', ai = 1 Q and az %3! %3D 0.2143 H, estimate the natural frequency, damping coefficient, and ringing frequency of the instrument. Plot the input and output signals for an input signal of F(t) = (4.4 m/s) U(t). Determine the 90% rise time and settling time from the plot. Label the transient and steady parts of the curve.
