Question

The displacement, d, in millimeters of a tuning fork as a function of time, t, in seconds can be modeled with the equation d=0.4 sin(1760rt). What is the maximum displacement of the tuning fork?

a. 0.2 mm
b. 0.4 mm
c. 0.8 mm
d. 2.5 mm

Answer 1

I think you can use the maximum displacement of the sine
maximum displacement = 0.4 * maximum of sin

Answer 2

im not sure what the rt stands for in sin(1760 `rt`)

Answer 3

rate of time

Answer 4
