A sound wave has a propagation speed of 349 m/s, a frequency1026 Hz, and has a maximum displacement of ym=3.02x10-7 m. At time t= 0, and x= 0, the displacement isym = 1.00x10-7 m.
(a) Using these values, find an equation of form:
        y(x,t) =ym sin(kx - ωt + ϕ)
(b) Differentiate the expression and find the maximum speed ofthe oscillating air molecules.
(c) Find the maximum magnitude of acceleration of theoscillating air molecules.
