Applying law of conservation of momentum,
Mv= m1v1 + m2v2 +m3v3
As initially M is at rest ,v= O
Also m1=m2 =m3 = m (equal masses)
We have m(v1 +v2+ v3) = O
v1+ v2 = -v3
(3i+2j)+(-i-4j) = -v3
3i+2j-i-4j =2i-2j =-v3
v3 = -2i+2j

You can apply law of conservation of momentum,

Mv= m1v1 + m2v2 +m3v3

as initially M is at rest ,v= O

also m1=m2 =m3 = m (equal masses)


We have m(v1 +v2+ v3) = O


v1+ v2 = -v3

(3i+2j)+(-i-4j) = -v3

3i+2j-i-4j =2i-2j =-v3


v3 = -2i+2j

option c
