Homework Help Overview

The problem involves a particle moving along the x-axis with a given acceleration function a(t) = t + sin(t) and an initial velocity of -2 at t = 0. The question seeks to determine the time t when the particle's velocity becomes zero.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between acceleration and velocity, with one noting the need to find the velocity function from the acceleration. There is also mention of a participant who claims to have resolved the question independently.

Discussion Status

The discussion includes attempts to clarify the requirements for posting in the Homework section, with some participants acknowledging their lack of familiarity with the forum's guidelines. There is no explicit consensus on the solution, but the conversation reflects a mix of exploration and procedural clarification.

Contextual Notes

Participants reference the forum's posting rules and express uncertainty about the proper use of the Homework section, indicating a potential barrier to effective discussion.

At time t is greater than or equal to 0, the acceleration of a particle moving on the x-axis is a(t)= t+ sin t. At t=0, the velocity of the particle is -2. For what value t will the velocity of the particle be zero?

The sticky at the top will show you what is required for posting Homework questions.

I'll go ahead and tell you that all you basically need to know is how to find velocity (v(t)), when given acceleration (a(t)). It's quite simple and after that the question basically answers itself.
 
yeah i actually figured it out already
i couldn't figure out how to delete it
 
A mentor will probably delete or move this. I'd take note of the Homework sections and proper use though.
 
yeah i didnt know about that
