85. A material point performs harmonic oscillations according to the equation x = 0,02cos (πt + π / 2), m. To determine: 1) the amplitude of the oscillations; 2) the period of oscillation; 3) The initial phase of the oscillations; 4) The maximum speed of the point; 5) the maximum acceleration point; 6) How long after the beginning of the reference point will pass through the equilibrium position.
