An object with a mass of 41.0 g is moving uniformly with a velocity of 37.0 m/s along the positive x-axis. A second object, of mass 38.0 g, is moving at +10.0 m/s along the same line, in front of the first mass.

1. What is the velocity of the first particle, in the zero momentum frame, after an elastic collision?

2. Using your answer from the previous question, determine the velocity in the laboratory frame, of the first particle after an elastic collision.
