###### A hand grenade is thrown with speed $v_{0}=30 \mathrm{m} / \mathrm{s},$ as sketched in Figure $\mathrm{P} 7.51$, just prior to exploding. It breaks into two pieces of equal mass after the explosion. One piece has a final velocity of $40 \mathrm{m} / \mathrm{s}$ along $x$. Find the velocity of the other piece after the explosion.
