3. On a frictionless air track, a 0.5000 kg-glider moving to the right at 2.900 m/s collides with a 0.8000 kg glider moving to the left at 1.900 m/s. The collision is inelastic. Assume the rightward direction is the positive direction of motion. THE COLLISION IN COMPLETELY INELASTIC. THUS, THE TWO GLIDERS STICK TOGETHER (WITH VELCRO), AND AFTER THE COLLISION MOVE TOGETHER WITH A COMMON VELOCITY V f. (a) (b) What is COMMON velocity Vf of the two gliders after the collision? What direction do the coupled gliders move after the collision, rightward or leftward? SHOW THAT KINETIC ENERGY IS NOTCONSERVED IN THE COLLISION.
