Задача 40326.

The elastic wave propagates along the x axis at a speed of 20 m / s. Medium particle oscillation period is T = 2, the amplitude A = 0.5 cm. Determine the wavelength displacement, velocity and acceleration of a point located on the vibration source at a distance x = 5 m at time 0.5 seconds.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
