One Dimension Free-Fall Problem

Click For Summary

Homework Help Overview

The discussion revolves around a one-dimensional free-fall problem involving a scenario where one person throws a ball to another, with specific timing and distance considerations. The participants are exploring the physics of projectile motion and the calculations related to initial velocity.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to use a system of equations to determine the initial velocity of the ball but expresses confusion regarding the results. There are questions about the validity of the calculated initial velocity and its fit within the position equation.

Discussion Status

Participants are actively engaging with the problem, with some expressing frustration over the lack of resolution. There is an ongoing exploration of the calculations and assumptions made regarding the initial velocity, but no consensus has been reached.

Contextual Notes

Participants note that the initial velocity calculated is 16.66 m/s, but there are concerns that this value does not align with other aspects of the problem, indicating potential misunderstandings or miscalculations in the setup.

5. Sue is watching Hugh 7.2 meters below her when she sees him throw a ball up to hit her. She pulls in her head, but Hugh purposely threw the ball hard enough to hit her on his way down 1 second after it passes her on the way up. Explain how hugh figured this out...

I used a sort of system of equations...but it is comin out to 16.66 as the Vo, but when i plug it into the equation, it doesn't fit the other times

come on ya'll, i need some real help
 
woah EASYYYY on the help
 
this is the best help site EVVAR
 
everyone keep viewing and not helping, i keep gettin 16.66, EVERY WAY I TRY, but that doesn't fit the position equation correctly
 
16.66 for the initial velocity BY THE WAY
