Tn free space, a 4.0 kg shell passes the origin of an inertial frame at the instant t = 0 moving with a velocity 2.5 m/s in the positive x-direction elative to the frame. Thereafter it explodes into three fragments A, B and C of masses 2.0 kg, 1.0 kg and 1.0 kg respectively. At the instant t - 10 s, the fragment A is observed at position (85, 80, 64) moving with velocity (10i +10j+8k) m/s and fragment B at position (-35, 0, -64) moving in the x-z plane. Find velocity vector of the fragment C. All the oordinates are given in metres. Ans: -(5î + 20+8€) mLs
