A bomb at rest at the origin of an xy-coordinate system explodes
into three pieces. Just after the explosion, one piece, of mass 4
kg, moves with a velocity of 45 m/s in the negative x-direction,
and a second piece, also of mass 4 kg, moves with a velocity of 36
m/s in the negative y-direction. The third piece has a mass of 7
kg.
What is the initial momentum of the bomb before the
explosion?
What is the x-component...
