$\vec{p}_1$ impulsli 1-sharcha $\vec{p}_2$ impulsli 2-sharcha bilan elastik to‘qnashdi. 1-sharcha harakatini $\vec{p}_3$ impuls bilan davom ettirgan bo‘lsa, 2-sharchaning keyingi impulsi quyidagilarning qaysi biriga teng?

1. A$\vec{p}_1-\vec{p}_2-\vec{p}_3$
2. B$\vec{p}_1+\vec{p}_2-\vec{p}_3$
3. C$\vec{p}_1+\vec{p}_3-\vec{p}_2$
4. D$\vec{p}_3+\vec{p}_2-\vec{p}_1$
