True or False. Consider the sum of harmonic motions, (x(t)=x_{1}(t)+x_{2}(t)=A cos (omega t+alpha)), with (x_{1}(t)=15 cos omega

Question:

True or False.

Consider the sum of harmonic motions, \(x(t)=x_{1}(t)+x_{2}(t)=A \cos (\omega t+\alpha)\), with \(x_{1}(t)=15 \cos \omega t\) and \(x_{2}(t)=20 \cos (\omega t+1)\). The amplitude \(A\) is given by 30.8088 .
