Answer 5

Recall the momentum equation: \[p=mv\]
Conservation of momentum is given by: \[m _{1}v _{1}+m _{2}v _{2} = (m _{1}+m _{2})v _{f}\]
In this case, the second object's velocity is zero, which edits the equation to be: \[m _{1}v _{1} = (m _{1}+m _{2})v _{f}\]
So to solve for the final velocity, you would have: \[v _{f}=v _{1}\frac{ m _{1} }{ m _{1}+m _{2} }\]
