A pelican flying along a horizontal path

Click For Summary

Homework Help Overview

The problem involves a pelican flying horizontally and dropping a fish from a height of 5.4 meters, with the fish traveling 8.0 meters horizontally before hitting the water. The focus is on determining the pelican's initial speed.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the vertical and horizontal components of motion, questioning how to calculate the time it takes for the fish to fall and which kinematic equations apply to the scenario.

Discussion Status

The discussion is ongoing, with participants exploring the appropriate kinematic equations and questioning the validity of certain equations presented. There is an emphasis on clarifying the relationships between the variables involved.

Contextual Notes

Some participants express uncertainty about the correct kinematic equations to use, and there is a mention of a resource listing basic equations of 1-D kinematics, indicating a need for clarification on the subject matter.

a pelican flying along a horizontal path...

A pelican flying along a horizontal path drops a fish from a height of 5.4 m. The fish travels 8.0 m horizontally before it hits the watwe below. What was the pelican's initial speed?


Well I'm guessing that y =-5.4m and x= 8.0 m...what do I exactly do after...meaning how do I solve this?

How long does it take to fall 5.4 m? What kinematic equations describe the vertical motion?
 


Y=viy+at?

Y=viy+at?
No. Where did you get that equation? (Note that each term in that equation has different units, so it cannot possibly represent something real.)

Look here for a list of kinematic equations: Basic Equations of 1-D Kinematics
