A block of mass \(m\) is initially at rest at position \(x = 0\) on a frictionless horizontal surface. Beginning at time \(t = 0\), a time-dependent horizontal force \(F(t) = F_0 \sin(\omega t)\) is applied to the block in the positive \(x\)-direction, where \(F_0\) and \(\omega\) are positive constants. Which of the following expressions represents the maximum speed \(v_{\text{max}}\) attained by the block?
