Guitar string is pulled at point P distance of 3 cm above its rest position. It is then released and vibrates in damped harmonic motion with the frequency of 165 cycles per second. After 2 s, it is observed that amplitude of vibration at point p is 0.6 cm
(a) Determine damping constant c
(b) Determine the equation which explains position of point P above its res position as the function of time. Take t=0 to be instant that string is released.
