Homework Help Overview

The discussion revolves around a rotational motion problem involving a heavy ball connected to a light rope, with specific acceleration values given at different times. Participants are trying to determine the acceleration at an earlier time based on limited information provided in the problem statement.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the completeness of the problem and what additional information might be necessary to solve it. There is discussion about whether the acceleration is constant or varies over time, and how that affects the interpretation of the problem.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem and raising questions about the assumptions involved. There is no explicit consensus yet on how to proceed, but the dialogue is focused on clarifying the information needed for a solution.

Contextual Notes

Participants note the lack of clarity regarding the constancy of acceleration and the initial conditions of the motion, which are critical to solving the problem.

Hey everyone,

Okay, so I'm just not sure how to solve this problem exactly and could use some kind advice.

A heavy ball is connected on the end of a light rope and undergoing rotation witha radius of X, let's say. At t= 19.3s a=10.2m/s^2. At t=7.4s what was the acceleration.

How does one go about solving this problem? Thanks in advance.

Is that the entirety of the problem? There isn't enough information as it currently stands to solve this.
 
honestly I don't remember exactly what the problem stated...but I know there wasn't much more info...what info would be needed to solve this?
 
why do you say that daveb?
 
I say that because the problem doesn't state whether acceleration is constant (magnitude) or varied.
 
what if it said it started from rest? And would it be fair to say that the acceleration is NOT constant since it's asking for the acceleration at some earlier point in time? This question has baffled me a bit...
