What This Document Is
This document contains worked solutions to a homework assignment for Physics I for Engineering Students (33 106) at Carnegie Mellon University, specifically covering material from the second week of the course. It addresses problems related to kinematics – the description of motion – including concepts like velocity, displacement, and acceleration.
Why This Document Matters
This resource is intended for students enrolled in the specified physics course who are seeking to check their understanding of the homework problems. It’s most valuable *after* a student has attempted the problems independently, as a way to verify their approach and identify areas where they may have made errors. It serves as a study aid to reinforce concepts covered in lectures and the course textbook.
Common Limitations or Challenges
This document provides solutions, but it does not offer detailed explanations of the underlying physics principles. It assumes the student has a foundational understanding of kinematics and is primarily focused on applying those principles to solve specific problems. It won’t substitute for attending lectures, reading the textbook, or actively participating in problem-solving sessions.
What This Document Provides
The full document includes complete solutions for two problems:
* Problem 1 involves analyzing the motion of a gazelle based on a velocity-time graph, calculating total distance, displacement, and sketching an acceleration-time graph.
* Problem 2 focuses on the motion of a turtle described by a position function, determining initial velocity, initial position, acceleration, and times when the turtle returns to its starting point or is a specific distance from it.
This preview does *not* include the detailed calculations or the complete acceleration-time graph sketch. It only describes the types of problems addressed and the concepts involved.
