A vessel at rest at the origin of an xy coordinate
system explodes into three pieces. Just after the explosion, one
piece, of mass m, moves with velocity (-22 m/s) î and a
second piece, also of mass m, moves with velocity (-22
m/s) ĵ. The third piece has mass 3m. Just after the
explosion, what are the (a) magnitude and
(b) direction (as an angle relative to the
+x axis) of the velocity of the third piece?
