Question

Given the equation for simple harmonic motion d=2.3cos(4pi/3 t)

a.find the maximum displacement
b.find the frequency
c.calculate the horizontal displacement at t=3 seconds

Answer 1

\[x=x_mcos(\omega t)\]\[x_m(\max.disp)=2.3m\]\[\omega =4 \pi/3=4.19 rads/\sec\]\[d(3 secs)=2.3\cos(\frac{ 4 \pi }{ 3}\times3)=2.3m\]

Am I correct?
