Potential energy \(U(x)\) and total mechanical energy \(E\) versus position \(x\).
Potential energy \(U(x)\) and total mechanical energy \(E\) versus position \(x\).
An object of mass \(0.50\text{ kg}\) attached to an ideal horizontal spring undergoes simple harmonic motion on a frictionless surface. The graph shows the potential energy \(U(x)\) of the system and the total mechanical energy \(E\) of the object-spring system as functions of position \(x\).

What is the magnitude of the acceleration of the object when it is at position \(x = 0.30\text{ m}\)?
