Recall that the relative velocity is independent of the reference frame, \[\overrightarrow{\mathbf{v}}_{1, i}-\overrightarrow{\mathbf{v}}_{2, i}=\overrightarrow{\mathbf{v}}_{1, i}^{\prime}-\overrighta...Recall that the relative velocity is independent of the reference frame, →v1,i−→v2,i=→v′1,i−→v′2,i In the laboratory reference frame →v2,i=→0, hence the initial relative velocity is \(\overrightarrow{\mathbf{v}}_{1,2, i}^{\prime}=\overrightarrow{\mathbf{v}}_{1,2, i}=\overrightarrow{\mathbf{v}}…
