A 0.145 kilogram glider is moving to the right on a frictionless, horizontal air track with a speed of 0.81 meter per second. It has a head-on collision with a 0.290 kilogram glider that is moving to the left with a speed of 2.26 m/s. Obtain the final velocity of each glider if the collision is elastic.
