A student is studying simple harmonic motion of a spring. She conducts an experiment where she measures the amplitude and period of an undamped system to be 27+/-1 mm and 0.40 +/-0.020 seconds, respectively. Using the equation for displacement as a function of time y (t)= Acos (wt), what is the uncertainty of her displacement calculation in mm for t-0.050+/-0.0010 seconds?
