The movement of a material point as a result of the addition of 2 mutually perpendicular harmonic oscillations of the same frequencies, amplitudes and different phases of oscillations by n / 2 occurs along a circle with a radius of 5 cm at a constant speed of 10 cm / s clockwise. Calculate the amplitude, frequency of oscillations and write the equations of oscillations x (t) and y (t) in explicit form.

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 try to help.
