Please solve with steps

(a) Quartz tuning fork oscillators, commonly used to control the timing of wristwatches, have become popular in nanotechnology sensor applications. A quartz oscillator has an effective spring constant of 37260 Nm 1, effective mass of 0.879 mg and an amplitude of 1.6 um. Assuming the fork is at its maximum position at t = 0, write an equation for the displacement as a function of time. (b) Determine the acceleration of the tuning fork at t. = 0.163 ms
