Задача 40532.

The equation of continuous oscillations is given in the form x = 4sin (nt) cm. Find the displacement from the equilibrium position of a point located at a distance of 75 cm from the oscillation source, 0.01 s after the beginning of oscillations. The speed of propagation of vibrations is 300 m / s.

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