Solve 3D Kinematics Problem with Homework Equations | Attempted Solution

Click For Summary
SUMMARY

The forum discussion centers on solving a 3D kinematics problem related to the horizontal range of a plane. The user initially misinterpreted the horizontal range as a distance to the east, rather than understanding it as the distance from the radar site excluding altitude. The clarification provided by another user emphasized the correct interpretation of horizontal range in terms of x and y coordinates. This insight led to a resolution of the misunderstanding regarding the homework equations.

PREREQUISITES
  • Understanding of 3D kinematics principles
  • Familiarity with horizontal range concepts in physics
  • Knowledge of coordinate systems (x, y, z)
  • Experience with homework problem-solving techniques
NEXT STEPS
  • Research 3D kinematics equations and their applications
  • Study the concept of horizontal range in projectile motion
  • Learn about coordinate transformations in physics
  • Explore common pitfalls in interpreting physics problems
USEFUL FOR

Students studying physics, particularly those tackling kinematics problems, educators teaching these concepts, and anyone seeking to improve their problem-solving skills in 3D motion scenarios.

The Attempt at a Solution


This is my work for this problem. Disregard the drawing as it isn't right.

I'm not sure if I'm misinterpreting the horizontal range part or what. I feel pretty confident about my work but webassign says it's wrong and I don't really see why.

The horizontal range of the plane means its distance from the radar site without including the plane's altitude.
You are treating the horizontal range as the distance to the east, which is incorrect.

Ahhh. You were absolutely spot on. I was unaware that they were using horizontal in the sense of x and y. Thank you very much.
