2\,\text{kg}

block moving at

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

collides head-on with a

3\,\text{kg}

block initially at rest. If the coefficient of restitution for the collision is

0.5

, calculate the speed of the

3\,\text{kg}

block just after the impact. (a)

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

(b)

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

(c)

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

(d)

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