guitar string a guitar string is pulled at point p a distance of 3 cm above its rest position. it is then released and vibrates in damped harmonic motion with a frequency of 165 cycles per second. after 2 s, it is observed that the amplitude of the vibration at point p is 0.6 cm (a) Find the damping constant c. (Round your answer to two decimal places.) (b). Using the values given above, find an equation that describes the position of point P above its rest position as a function of time. Take t=0 to be the instant that the string is released. (Round your coefficients to two decimal places.)
