The displacement, d, in millimeters of a tuning fork as a function of time, t, in seconds can be modeled with the equation mc001-1.jpg. what is the maximum displacement of the tuning fork? 0.2 mm 0.4 mm 0.8 mm 2.5 mm

The model of a sin function with a maximum displacement A, is given by

Given that the displacement, d, in millimeters of a tuning fork as a function of time, t, in seconds can be modeled with the equation d = 0.4sin(1760 pi t).

Then, the maximum displacement is 0.4.
