An object with mass $3.0\,\text{kg}$, moving at $6.0\,\text{m s}^{-1}$, collides with an object of mass $2.0\,\text{kg}$ that is moving in the opposite direction at $2.0\,\text{m s}^{-1}$. The two objects remain joined together in the collision. What are the speed and direction of the total mass after the collision?
- A$4.4\,\text{m s}^{-1}$ to the left
- B$4.4\,\text{m s}^{-1}$ to the right
- C$2.8\,\text{m s}^{-1}$ to the left
- D$2.8\,\text{m s}^{-1}$ to the right
