# A block of mass \(m\) attached to an ideal horizontal spring undergoes simple harmonic motion with amplitude \(A\) on a frictionless surface. The maximum speed of the block during its oscillation is \(2.0 \text{ m/s}\). What is the speed of the block when its displacement from equilibrium is \(x = \dfrac{1}{2}A\)?

A block of mass \(m\) attached to an ideal horizontal spring undergoes simple harmonic motion with amplitude \(A\) on a frictionless surface. The maximum speed of the block during its oscillation is \(2.0 \text{ m/s}\). What is the speed of the block when its displacement from equilibrium is \(x = \dfrac{1}{2}A\)?

![A horizontal mass-spring system on a flat surface. A block is attached to a horizontal spring fixed to a vertical wall on the left. The equilibrium position x = 0 is marked with a dashed vertical line. Oscillation boundaries are indicated at x = -A and x = +A, and the block is positioned at x = A/2 to the right of equilibrium. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787460311-hfy6Lh.jpg)
