Question

24. The displacement of a harmonic oscillator is given by x= asinut + bcoswt. What the amplitude
of the oscillation?

Answer 1

Answer:

Amplitude is the magnitude of change in the oscillating variable with each oscillation within an oscillating system. ... In audio system measurements, telecommunications and other areas where the measured is a signal that swings above and below a zero value but is not sinusoidal, peak amplitude is often used.

Explanation:

f=ma=-kX,where k is spring constant, x is the displcement and a is the acceleration. the max x is Acos(o,or pi.or 2pi)=A,since cos 0=cospi=cos2pi=1,so the amplitude A=X which is th maxmimum displacement.
