${\underline{\red{Answer:}}}$

0.02 m/s, option D (none of these)

${\underline{\red{Formula:}}}$

$v = \frac{m_1v_1 + m_2v_2}{m_1 + m_2}$

${\underline{\green{Solution:}}}$

$v = \frac{m_1v_1 + m_2v_2}{m_1 + m_2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = \frac{(200)(0.05) + (150)(0)}{200 + 150} \\ = \frac{10}{350} = 0.02 \: m {s}^{ - 1} \: \: \: \: \: \: \: \: \: \: \:$
