A $65$ g object on a frictionless surface is attached to an ideal horizontal spring with a spring constant of $2\mathrm{.}1{10}^2\frac{N}{m}.$ You start the object oscillating by pulling it $2\mathrm{.}0$ cm from the equilibrium position and releasing it$.$

What is the speed $($units: $\frac{m}{s})$ of the object as it passes through the equilibrium position?
