Question 29 POST_UTME_OAU • 2020 • PHYSICS • objective

A simple harmonic motion is described by the equation $x = A \cos $ \omega t + \phi $$. If the amplitude is $A = 2$ and the phase angle is $\phi = \frac{\pi}{4}$, find the equation of the motion.

Correct Answer A. $x = 2 \cos \left\( \omega t + \frac{\pi}{4}\right)\ $

B. $x = 2 \sin \left\( \omega t + \frac{\pi}{4}\right)\ $

C. $x = 2 \cos \left\( \omega t - \frac{\pi}{4}\right)\ $

D. $x = 2 \sin \left\( \omega t - \frac{\pi}{4}\right)\ $

Correct Answer

Correct Option:

$x = 2 \cos \left\( \omega t + \frac{\pi}{4}\right)\ $
