Question 39 POST_UTME_UNILORIN • 2022 • PHYSICS • objective

A block of mass $m$ is attached to a spring with spring cons\tant $k$. If the block is displaced by a dis\tance $x$ from its equilibrium position and released from rest, find the velocity $v$ of the block as a function of time $t$.

Answer Options

A. v(t) = \sqrt{\frac{k}{m}} x \cos\( \sqrt{\frac{k}{m}} t \)
Correct Answer B. v(t) = \sqrt{\frac{k}{m}} x \sin\( \sqrt{\frac{k}{m}} t \)
C. v(t) = \sqrt{\frac{k}{m}} x \cos\( \sqrt{\frac{k}{m}} t \)
D. v(t) = \sqrt{\frac{k}{m}} x \sin\( \sqrt{\frac{k}{m}} t \)
Correct Answer
B
Correct Option:
v(t) = \sqrt{\frac{k}{m}} x \sin\( \sqrt{\frac{k}{m}} t \)
