Question

A 9300kg car traveling at a velocity of 5m/s strikes a second boxcar that weighs 5000kg at rest.At what speed will the second boxcar move?

Answer 1

$\begin{gathered} \text{For car} \\ v_1=\text{ }5\text{ m/s} \\ m^{}_1=9300\operatorname{kg} \\ \text{For b}oxcar \\ m_2=5000\operatorname{kg} \\ v_2=? \\ v_2=\frac{2m^{}_1}{m^{}_1+m^{}_2}v_1 \\ \end{gathered}$
