Answer: 4.24 kg ⋅ m/s
Explanation:
[tex]$The total momentum of the system is given by:$p=\sqrt{p_{1}^{2}+p_{2}^{2}}$According to the information provided, the momentum of first system $p_{1}$ is equal to momentum of second system $p_{2}$$\begin{aligned}&p=\sqrt{2 p_{1}^{2}} \\&=\sqrt{2 \cdot(0.100 \mathrm{~kg} \times 30 \mathrm{~m} / \mathrm{s})^{2}} \\&p=4.24 \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}\end{aligned}$[/tex]
