Задача id10164

Oscillations propagate along a certain straight line with a period of 0.25 s and a speed of 48 m/s. 10 s after the occurrence of oscillations at the initial point, at a distance of 43 m from it, the displacement of the point turned out to be equal to 3 cm. At the same time, determine the displacement and phase of the oscillation at a point 45 m from the source of oscillations.
