Задача 10632.

Point performs harmonic oscillations, the equation which has the form x = 5sin2t. At a time when the point of acting the restoring force of 5 x 10 -3 N, the point has the potential energy of 10 ^ -4 George. Find this point in time and the corresponding phase of the oscillation.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
