An object flying in air with velocity $\displaystyle (20 \hat{i}+25 \hat{j}-12 \hat{k})$ suddenly breaks into two pieces whose masses are in the ratio $\displaystyle 1$ : 5. The smaller mass flies off with a velocity $\displaystyle (100 \hat{\mathrm{i}}+35 \hat{\mathrm{j}}+8 \hat{\mathrm{k}})$. The velocity of the larger piece will be.
Official answer
(1)
$\displaystyle 4 \hat{\mathrm{i}}+23 \hat{\mathrm{j}}-16 \hat{\mathrm{k}}$
