Question

A particle A, of mass 8 kg, collides with
a particle B, of mass m2 kg. The velocity
of particle A before the collision was (-1i
+4j) ms-1 and the velocity of particle B
before the collision was (-0.8i +1.4j) m
s-1. Given the velocity of particle A after
the cwlision was(-2i +2j) s-1, anjthe
velocity of particle B was 3j m s-1, what
was the mass of particle B?​
