1.5\,\text{kg}

trolley is moving due east at

10\,\text{m/s}

. After turning a corner it moves due south at

6\,\text{m/s}

. Calculate the magnitude of the change in momentum of the trolley. a)

6\;\text{kg}\cdot\text{m/s}

24\;\text{kg}\cdot\text{m/s}

17.5\;\text{kg}\cdot\text{m/s}

15\;\text{kg}\cdot\text{m/s}
