A simple harmonic oscillation is represented by `y=0.40sin(440t+0.61)` in SI units. Find angular frequency of oscillation

Text Solution

Verified by Experts

We are given : `y=0.40sin (440t+0.61)`.
We are to calculate, amplitude (A) and time period (T)
Comparing this equation with, `y=a sin (omegat+phi)` we get
Angular frequency `omega=2piv=440" or "v=(440)/(2xxpi)=(440xx7)/(2xx22)=70Hz`
