If the amplitude of the motion is $0\mathrm{.}075$ mm and the period of $1\mathrm{.}00$ ss$,$ where is the object $0\mathrm{.}35$ ss after it has passed the equilibrium position, moving downward?

Express your answer with the appropriate units. Enter positive value if the object is above the equilibrium position and negative value if the object is below the equilibrium position.
