Question 21 POST_UTME_IMS_U • 2018 • PHYSICS • objective

A particle of mass $m$ is attached to a spring with spring cons\tant $k$. The particle is displaced by a dis\tance $x_0$ from its equilibrium position and released from rest. Assuming the motion is simple harmonic, find the time $t$ at which the particle's velocity is $v = \frac{dx}{dt} = -omega x_0 \sqrt{1 - \cos^2 omega t}$, where $omega = \sqrt{\frac{k}{m}}$.

Correct Answer A. t = \frac{\pi}{2\omega}

B. t = \frac{\pi}{4\omega}

C. t = \\frac{3\\pi}{4\\omega}

D. t = \frac{\pi}{\omega}

Correct Answer

Correct Option:

t = \frac{\pi}{2\omega}
