the graphical method to of: Use find the step response

An accelerometer is used to detect ultra-low-level, low-frequency vibrations (100 Hz)associated with very large structures. It possesses a natural frequency of 1000 Hz witha damping ratio of 0.05 and sensitivity of 2V/g. Write down the order of the systemand its differential equation

LOOP GAIN( NEED ONLY HANDWRITTEN SOLUTION PLEASE OTHERWISE DOWNVOTE).

Design RLC circuits for underdamped, overdampt and critically damped response (one circuit per response). Use Vpp < 5V, show all your calculations and simulation. Use the component values.
