Rectilinear Motion of Particle

Click For Summary

Homework Help Overview

The problem involves the rectilinear motion of a particle, where the acceleration is directly proportional to time. Initial conditions include a velocity of -12 m/s at t=0, with additional conditions at t=4s where the velocity is 0 and the position is 15.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for an attachment to verify the original poster's solution and express concerns about the format of the submission. There are suggestions to write the solution in plain text instead of PDF. Some participants question the integration process used to find the position function.

Discussion Status

The discussion is ongoing, with participants waiting for the attachment approval and expressing a willingness to help once the original poster shares their attempt. There is a recognition of the need for clarity in the integration process, and some participants are exploring different approaches to the problem.

Contextual Notes

There is mention of forum rules that restrict assistance until the original poster provides their solution attempt. Participants are also navigating the challenges of using the forum's formatting features for mathematical expressions.

Homework Statement



3. The acceleration of a particle is directly proportional to the time t. At t=0, the velocity of a particle = -12 m/s. Knowing that v=0 and x = 15 when t=4s, write the equation of the motion.

Here is my solution, could Somebody check it?

I'm still waiting for the attachment approval. In the meantime, dzien dobry.
 
Dzien dobry :)) Attachment approval? So you cannot look into it?
 
You have explained the problem well enough, and I believe I can solve it, but it is against forum rules for me to provide any help until I see your attempt at a solution. Is there a reason why you need to put it into pdf format? I understand that using the tex feature on this forum is a bit frustrating, but you can just try to write out your solution in plane text here, and I will try to follow it.
 
When you integrated v to find x as a function of t, you did something wrong. I advise you to put limits on your integration, and put explicitly what is the differential quantity over which you're integrating.
 
do you have any other simplier sulotion for rectilinear motion??
 
adashiu's approach is the simplest approach that I'm aware of. In fact, off the top of my head, I can't think of another way to do it.
