A bomb at rest at the origin of an xy-coordinate system explodesinto three pieces. Just after the explosion, one piece, of mass 4kg, 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 36m/s in the negative y-direction. The third piece has a mass of 7kg.
What is the initial momentum of the bomb before theexplosion?
What is the x-component of the velocity of the third piece justafter the explosion?
What is the y-component of the velocity of the third piece justafter the explosion?
What is the magnitude of the velocity of the third piece?
Just after the explosion, in what direction is the third piecemoving? (Give your answer as an angle measured clockwise from thepositive x-axis.)
