Question

A harmonic oscillation is represented by y=0.34 cos (3000t+0.74), where y and t are in mm and s respectively. Deduce (i) and amplitude (ii) the frequency and angular frequency (iii) the period and (iv) the intial phase.

Answer 1

Correct Answer - (i) 0.34m
(ii). `(1500)/(pi)Hz,3000rads^(-1), (iii). `(pi)/(1500)s`
(iv). `0.74rad`
