A shell moving with a velocity Vo = (12.8 m/s)i – (9.8 m/s)j - (368 m/s)k explodes at point D into three fragments A, B, and C of mass, respectively, 3.69 kg, 2.69 kg, and 1.69 kg. Knowing that the fragments hit the vertical wall at the points indicated, determine the speed of each fragment immediately after the explosion. Assume that elevation changes due to gravity may be neglected.
