Hey everyone, i need a hand with a question i have for an assignment...
a guitar string is vibrating in its fundamental mode, with a node at both ends. Given the length (0.390m). The max transverse acceleration at a point in the middle of the string (8900m/s^2) and max transverse velocity of 4.00 m/s
how do i find the amplitude?
i know the equation of a standing wave is y(x,t)= Asin(kx)sin(wt)
where a is the amplitude of the standing wave and w denotes omega
in the fundamental mode the wavelength is 2L...
but im not sure where to start... can anyone point me in the right direction?
