Alright 👑ApN~Glam👑 — let's do this.
Step 1: Define initial conditions and set up equations for conservation of momentum and coefficient of restitution.
Let the direction of particle A's initial motion be positive.
Mass of particle A: $m_A = m$
Mass of particle B: $m_B = 3m$
Initial velocity of particle A: $u_A = 4u$
Initial velocity of particle B: $u_B = -u$ (since it's moving towards A)
Final velocity of particle A: $v_A$
Final velocity of particle B: $v_B$
Coefficient of restitution: $e
