Homework Help Overview

The discussion revolves around a free-fall problem involving two balls, one of which is thrown upward against gravity. Participants are exploring the graphical representation of the motion of these balls and the implications of their trajectories.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants are attempting to understand how to represent the motion of ball 2 in comparison to ball 1, questioning whether the points should be mirrored or adjusted based on the direction of the throw. There are inquiries about the meeting point of the two balls and which ball has traveled further.

Discussion Status

Some participants have offered guidance on how to approach the graphical representation, while others are seeking further clarification on the relationships between the balls' motions. Multiple interpretations of the problem are being explored, particularly regarding the initial conditions and the resulting trajectories.

Contextual Notes

There is a focus on the initial conditions of the problem, specifically the distinction between launching a ball upward versus a bouncing motion. Participants are also grappling with the implications of acceleration and distance traveled by each ball.

Homework Statement



I am just trying to get confirmation I am correct. Refer to the picture below, which shows the question and diagram.

I am working on 2, a)

Homework Equations


The Attempt at a Solution



So I am to draw for ball 2 as if I was throwing the ball upwards against gravity.

Now, would my line and points be the same as Ball 1, just flipped over? Any help on this question(2,a) would be great!
 
Physics news on Phys.org
Spinnor, the question is not asking to draw the points as if the ball bounced, but insted launched from t = 0

From what I understand, it would look the same, in terms of the points correct?

Thanks anyone for the help!
 
Can anyone else take a crack at it? Much appreciated, thanks!

Again... I am having troubles with 2, a) and b)
 
Draw the same set of points on the right and start at the bottom and number them 1,2,3,4,5. Once you do this you should be able to do the rest. They don't meet half way up, with a little thought you should come up with the answer.
 
Hey,

So would they meet between the 2nd and 3rd point?Can you help me out with this "Which ball has traveled further and why?"

My guess would be ball 2 because its initial acceleration is greater ?
 
Anyone else? Much appreciated!
