A flat acoustic wave has a period T = 3 ms, the amplitude A = 0.2 mm and a wavelength of 1.2 m. Medium point remote from the oscillation source by a distance l = 2 m, a: 1) the offset (x, t) at time t = 7 ms; 2) the speed and acceleration for the same point in time. The initial phase of the oscillations take zero.
