Question 13 POST_UTME_REDEEMERS_UNIVERSITY • 2020 • PHYSICS • objective

A block of mass $m$ is susp\ended from 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, its subsequent motion is described by the equation $x(t) = A \cos\( omega t + phi \)$, where $A$ is the amplitude of the motion, $omega$ is the angular frequency, and $phi$ is the phase angle. If the block is observed to have a maximum speed of $v_{max} = 2\sqrt{2} , \text{m/s}$, what is the value of the spring cons\tant $k$?
