An 8-kg shell moving with a velocity vo-(13.-11. -345) m/s explodes at Point D into three fragments A, B, and C of mass, respectively, 4 kg, 3 kg. and 1 kg. Knowing that the fragments hit the vertical wall at the points indicated, determine the speed of fragment A immediately after the explosion. Assume that elevation changes due to gravity may be neglected. Given: . . Initial mass 8 kg. initial velocity vo (13, -11, -345) m/s, explosion at - W Find: position (0, 0, 5) mass A 5m W 4 kg, final position of A=(-1.5,0,0) mass B 3 kg. final position of B= (4.5, 2.5, 0) - mass C 1 kg. final position of C = (0,-3,0) m Your Answer: 3m the speed of fragment A immediately after the explosion, (m/s) Answer Question 5 (1 point)
