**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 IS COMPLETELY INELASTIC.**

Thus, the two gliders stick together (with Velcro), and after the collision move together with a common velocity \( V_f \).

**(a)** What is the COMMON velocity \( V_f \) of the two gliders after the collision? What direction do the coupled gliders move after the collision, rightward or leftward?

**(b)** SHOW THAT KINETIC ENERGY IS *NOT* CONSERVED IN THE COLLISION.

---

**Explanation:**

This problem involves a completely inelastic collision between two gliders on a frictionless air track. In such a collision, the objects stick together after colliding and move with a common velocity. The task is to calculate this velocity and determine whether kinetic energy is conserved.
