A particle performs harmonic oscillations along the x axis about the equilibrium position x = 0. The oscillation frequency is w = 4.00 /s .At a certain moment of time the particle has a coordinate X0 = 25.0 cm and its velocity is equal to Vx0 = 100 cm/s.Find the coordinate x and the velocity Vx of the particle t = 2.40 s after that moment.
