Question

The following expression represents the displacement of a point as a function of time:

y(t) = 100 + 95sin(15t) + 55cos(15t)
What is the fundamental frequency in Hertz?

Answer 1

The fundamental frequency in Hertz for the given expression is 15.

Step-by-step explanation:

The given expression represents the displacement of a point as a function of time: y(t) = 100 + 95sin(15t) + 55cos(15t). To find the fundamental frequency in Hertz, we need to determine the frequency component with the highest amplitude. In this case, both the sine and cosine terms have the same angular frequency of 15, so the fundamental frequency is 15 Hertz.
