Homework Help Overview

The problem involves kinematics, specifically focusing on vector addition of velocities in the context of an airplane's travel against wind. The original poster presents a scenario where an airplane's velocity and wind velocity are given, but seeks to determine the displacement with direction.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Some participants question the completeness of the information provided, noting the absence of time, distance, or acceleration. Others suggest that the problem may require clarification regarding the effective velocity.

Discussion Status

The discussion is ongoing, with participants exploring the implications of missing information and questioning the validity of the provided equation. There is an acknowledgment that the problem may not be fully specified as intended.

Contextual Notes

Participants note that the lack of time in the problem statement could lead to ambiguity in determining displacement, and there is a suggestion that the question may have been incomplete.

Homework Statement


An airplane travels at 885 km/h [W35S]. Wind blows against the plane with a velocity of 150 km/h [E55N]. What's the displacement with direction?

Homework Equations


v=v1^2+v2^2sqrt

The Attempt at a Solution

We need more information. There is no time, distance, acceleration, or final velocity. At the moment, the displacement is theoretically infinite. Were you given any more information?
 
That's all I was given.

Seems like the question was supposed to specify a time, but it was left out. Just find the effective velocity.
By the way, your "relevant equation" makes no sense.
