4.0\,\text{kg}

cart is moving

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

to the east when it suddenly breaks into two pieces. A

1.5\,\text{kg}

fragment continues eastward at

5.0\,\text{m}\!\cdot\!\text{s}^{-1}

. Neglecting external forces, what is the velocity of the

2.5\,\text{kg}

fragment? (a)

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

east (b)

1.8\,\text{m}\!\cdot\!\text{s}^{-1}

west (c)

1.8\,\text{m}\!\cdot\!\text{s}^{-1}

east (d)

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