Final answer:
The question deals with finding the properties of a parallelogram given its coordinates and involves vector calculation.
Step-by-step explanation:
The student is asking about a specific mathematical problem involving vertices of a parallelogram and some vector calculations. The question mentions coordinates for the vertices of a parallelogram, which is a fundamental concept in coordinate geometry. It also relates to vector addition and potentially physics as it involves equations for projectile motion. Yet, based on the given vertices, it appears to focus primarily on geometry and vector addition.
