Task 40540.
The material point participates in two oscillations occurring in one direction. The oscillation frequencies are 20 Hz. The amplitude of the first oscillation is 3 cm; the second - 4 cm. The initial phase of the first oscillation is -0; the second - n / 2. Write the equation of the resulting oscillation and draw a figure with a vector representation of the oscillations.
A detailed solution with a brief record of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, please write. I try to help.
