2.0\,\text{kg}

cart glides east at

3.0\,\text{m}\,\text{s}^{-1}

on a level, frictionless track and collides with a

1.0\,\text{kg}

cart that is initially at rest. The carts stick together. What is their speed immediately after the collision? a)

1.5\,\text{m}\,\text{s}^{-1}

2.0\,\text{m}\,\text{s}^{-1}

2.45\,\text{m}\,\text{s}^{-1}

1.0\,\text{m}\,\text{s}^{-1}
