42. Suspended from the ceiling is a weight on a large spring that is oscillating up and down. The distance, d inches, between the location of the center of the mass of the weight after t seconds and the weight’s equilibrium location at t = 0 is modeled by the function d = 5 sin(4πt). What is the amplitude of the function?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

Amplitude refers to the maximum value that the physical quantity of vibration may reach. So the question is to ask us to find the maximum value of d. Since the maximum value of sinx is 1, dmax=5. Therefore J.
