A $218\frac{-}{\frac{?}{?}}(\frac{rmkg}{\frac{?}{?}})$ projectile, fired with a speed of $\frac{146}{\frac{?}{?}}(\{Vm\{Vm\frac{m}{s}\}\})$ at a $52\mathrm{.}0^|$circ$\}$Y$)())$ angle, breaks into three pieces of equal mass at the highest point of its arc $($where its velocity is horizontal$).$ Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally.

Part A

Determine the magnitude of the velocity of the third fragment immediately after the explosion.
