Post Utme Christopher University 2020 Physics Question 2
Practice objective / multiple choice question 2 from the 2020 Post Utme Christopher University Physics examination.
A simple harmonic motion is described by the equation \( \theta\( t \ \) = A \cos\( omega t + phi \)), where $A$ is the amplitude, $omega$ is the angular frequency, and $phi$ is the phase angle. If the amplitude is $A = 2$ cm, the angular frequency is $omega = 3$ rad/s, and the phase angle is $phi = \frac{pi}{4}$, what is the displacement of the particle at time $t = 2$ s?
