A ball weighing m = 10 kg collides with a ball weighing 4 kg. The speed of the first ball 4m/s, the second - 12 m / s. Find the total speed of the balls after impact in two cases: 1) a small ball catches up with a large ball moving in the same direction; 2) the balls move towards each other. Impact is considered direct, central, inelastic.
