College Physics: A Strategic Approach Volume 1 provides a systematic exploration of fundamental physics concepts through a structured, problem-solving lens. The book begins with basic motion and kinematics, gradually progressing to complex topics such as forces, energy, momentum, rotational dynamics, fluid mechanics, and wave phenomena. Each chapter builds upon the previous one, employing clear visual models, analytical techniques, and real-world applications to illustrate key ideas and enhance conceptual understanding. This strategic approach ensures that students not only learn the essential principles of physics but also develop the critical thinking skills needed to apply them effectively in various contexts.

Problem 1
Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and flies $500 \mathrm{~m}$ due east, then flies $400 \mathrm{~m}$ west, then $700 \mathrm{~m}$ east. How far is the bee from the hive?
