Homework Help Overview

The discussion revolves around determining the magnitude of the wind velocity as observed by a passenger on a ship moving eastward. The problem involves concepts of relative motion and two-dimensional motion, particularly in the context of the ship's speed and the angle of the smoke from the funnels.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the need to recognize the problem as one involving two-dimensional motion and relative velocities. There is an emphasis on understanding the relationships between the velocities of the ship, wind, and smoke. Some participants express confusion about how to approach the problem and question the relevance of the equations being used.

Discussion Status

The discussion is ongoing, with participants exploring various aspects of the problem. Some guidance has been offered regarding the nature of the motion involved, but there is no clear consensus on the next steps or methods to apply.

A passenger on a ship traveling due east with a speed of 13.38m/s observes that the stream from the ship's funnels make an angle 20 (degrees) with the ships wake. The wind is blowing from south to north. Assume the smoke acquires a velocity(with respect to the earth) equal to the velocity of the wind as it leaves the funnels. Whats the magnitude of the velocity of the wind.

OK, so how did you start, and where did you get stuck?

You have to show your work here.
 
alright so the forumal X=distance after object accelerates for time
X0=initial distance
v=velocity after object accelerates for time
V0=initial velocity
a=acceleration
t=time
v=v0+at
x=x0+v0t+1/2at 2 squared
plunging it in is where iam stuck
 
You're just randomly grabbing equations, which won't do. First of all you've got to recognize that this is a two dimensional motion problem. And the second thing is that this is a relative motion problem.

Let [itex]\vec{V}_{SE}[/itex] be the velocity of the ship relative to the Earth.
Let [itex]\vec{V}_{WE}[/itex] be the velocity of the wind relative to the Earth.
Let [itex]\vec{V}_{WS}[/itex] by the velocity of the wind relative to the ship.

First question: How are these three quantities related?
 
Lisa: For the last time, stop posting your question all over the site.

You have to work with us. We are not going to do this problem for you.
