Physics

Three objects are involved in a series of inelastic collisions:

Object A: mass 2 kg, moving at 6 m/s.

Object B: mass 3 kg, moving at 4 m/s in the same direction as A.

Object C: mass 1 kg, initially at rest.

First, A collides inelastically with B, and they stick together. Then, the combined system of A and B collides inelastically with C, and all three objects move with a common velocity.

What is the final common velocity of the three objects?
