Elastic collision:

$\displaystyle \begin{aligned} RSOA&=RSOS \\ 2.0-0&=v-(-0.50) \\ v&=1.5\text{ m }{{\text{s}}^{-1}} \end{aligned}$

PCOM:

$\displaystyle \begin{aligned} \Sigma {{p}_{i}}&=\Sigma {{p}_{f}} \\ {{m}_{p}}(2.0)&={{m}_{p}}(-0.50)+{{m}_{q}}(1.5) \\ \frac{{{m}_{p}}}{{{m}_{q}}}&=\frac{1.5}{2.5}&=\frac{3}{5} \end{aligned}$
