Answer:
Momentum of 2nd ball is
direction is given as
Explanation:
As we know that there is no external force on the system of balls so momentum before and after collision will be conserved
So we have
now after collision momentum of two balls is must be same as initial
so we have
so we have
for other component we have
Momentum of 2nd ball is given as
direction is given as
