A 2-kg block moving in the positive x direction with a speed of 5.0 m/s collides with a 3-kg block moving in the same direction with a speed of 2.0 m/s. After the collision the 3-kg block moves at 4.2 m/s. Find the velocity of the 2-kg block after the collision. Is the collision elastic or inelastic? Justify your answer.
