Question

For the simple harmonic motion described by the trigonometric function, find the maximum displacement. ​  ​

Quizplus · Accepted Answer

The maximum displacement of a simple harmonic motion described by the trigonometric function y = A sin(ωt + φ) is equal to the amplitude A. 
In the given function, the amplitude is indicated by the numerical value in front of the sine function, which is 7c in this case. 
Therefore, the maximum displacement is 7c. 
Option C is the only one that includes 7c in its numerical value.
