An object with mass $2\mathrm{.}2$ kg is executing simple harmonic motion, attached to a spring with spring constant $290$ N$/$m$.$ When the object is $0\mathrm{.}018$ m from its equilibrium position, it is moving with a speed of $0\mathrm{.}60$ m$/$s$.$ Calculate the amplitude of the motion. Calculate the maximum speed attained by the object.
