## Conceptual Physics (12th Edition)

a. The momentum is mv. In the order ABCD, the momenta are: $$p=9 \frac{kg \cdot m}{s}$$ $$p=10.2 \frac{kg \cdot m}{s}$$ $$p=9.6 \frac{kg \cdot m}{s}$$ $$p=10 \frac{kg \cdot m}{s}$$ b. The impulse is defined as the change in momentum. The order will be identical.
