A bomb of mass 6 kg initially at rest explodes in to three identical fragments. One
of the fragments moves with a velocity of10 3 / im s � , another fragment moves with
a velocity if � 10 j m/s, then the third fragment moves with a velocity of magnitude.

  1. momentum is conserved. so
    initial momentum is zero. So
    2*V1+2*V2+2*V3=0
    you are given v1, v2. so add them. Then if their sum is L i+Mj, then v3 must be -Li-Mj m/s
    and magnitude is sqrt(L^2+M^2)
