The vortex velocity distribution function for a two-dimensional coarsening nonconserved O(2) time-dependent Ginzburg-Landau model is determined numerically and compared to theoretical predictions. In agreement with these predictions the distribution function scales with the average vortex speed which is inversely proportional to t(x), where t is the time after the quench and x is near 1/2. We find the entire curve, including a large speed algebraic tail, in good agreement with the theory.
