## Conceptual Physics (12th Edition)

The total momentum before and after the collision is the same $$1.41 \frac{kg \cdot m}{s}$$
The momentum vectors are at right angles to each other. Find the magnitude of the combined momentum using the Pythagorean Theorem. $$(1 \frac{kg \cdot m}{s})^{2}+(1 \frac{kg \cdot m}{s})^{2} =p^{2}$$ $$p=1.41 \frac{kg \cdot m}{s}$$
