25% 2. A 7 kg shell moving with a velocity ve = (600 m/s) k explodes at Point C into two fragments A, and B of mass, 4 kg and 3 kg, respectively. Knowing that the fragments land at the coordinates A(-4,3,1) and B(3, -4, -2), determine the speed of each fragment immediately after the explosion. Assume that elevation changes due to gravity may be neglected. y+ Al43,) -4m B(3-1,2) -3m Clo,0,6) 6 m.
