Problem

A body

A

of mass 500 g has velocity

\mathbf{v}_A = 10\,\hat i + 6\,\hat j - 2\,\hat k\;\text{m s}^{-1}

. Another body

B

of mass 1.0 kg moves with velocity

\mathbf{v}_B = -4\,\hat i + 3\,\hat j + 8\,\hat k\;\text{m s}^{-1}

. Determine (i) the total momentum vector of the system and (ii) its magnitude, expressing your answer in kg·m·s⁻¹.
