Two balls with masses m₁ and m2 fly towards each other. The kinetic energy of the second ball is 20 times greater than the kinetic energy of the first. Between the balls there is an absolutely inelastic impact. Find at what ratio m₁ / m₂ the balls after the impact will move in the direction of motion of the first ball.
