Task 40459.
The amplitude of harmonic oscillations of a material point with a mass of 40 g is 2 * 10 ^ -2 m. The maximum speed is 0.1 m / s. Write the equation of oscillations, assuming that at the initial moment of time the displacement from the equilibrium position is equal to half the amplitude. Determine the force acting on the material point at time T / 3.
A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I try to help.
