A particle performs harmonic oscillations with a period of t=2.0 s. The amplitude of oscillations is 10 cm. Find the displacement, velocity and acceleration of the particle in 0.2 sec after it passes through its equilibrium position, if the beginning of the oscillations coincides with the equilibrium position.
