A 0.2 kg plastic ball moves with a velocity of 1.5 m/s. It collides with a second plastic ball of mass 1.8 kg, which is moving along the same line at a speed of 0.1 m/s. After the collision, both balls continue moving in the same, original direction. The speed of the 1.8 kg ball is 0.26 m/s. What is the new velocity of the 0.2 kg ball?
