141375 A body is at rest at \(x=0\). At \(t=0\), it starts moving in the positive \(x\)-direction with a constant acceleration. At the same instant, another body passes through \(x=0\) moving in the positive \(x\)-direction with a constant speed. The position of the first body is given by \(x_{1}(t)\) after time \(t\) and that of the second body by \(x_{2}\) (t) after the same time interval. Which of the following graphs correctly describes \(\left(\mathrm{x}_{1}-\mathrm{x}_{2}\right)\) as a function of time?
