A body of mass M at rest explodes into three pieces, in the ratio of masses $\displaystyle 1: 1: 2$. Two smaller pieces fly off perpendicular to each other with velocities of $\displaystyle 30 \mathrm{~ms}^{-1}$ and $\displaystyle 40 \mathrm{~ms}^{-1}$ respectively. The velocity of the third piece will be :
Official answer
(2)
$\displaystyle 25 \mathrm{~ms}^{-1}$
