Homework Help Overview

The discussion revolves around a linear problems context, specifically focusing on finding the time (t) in relation to motion equations. Participants are exploring various approaches to the problem while adhering to forum guidelines regarding effort disclosure.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Some participants express a desire for different perspectives and approaches to the questions posed. Others inquire about the original poster's reasoning and the specifics of their disagreements with textbook solutions. There are hints provided regarding the equations of motion and the importance of initial conditions.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the original poster's attempts and reasoning. Some guidance has been offered in the form of hints, but there is no consensus on the solutions or approaches yet.

Contextual Notes

Participants are reminded of the forum's posting guidelines, emphasizing the necessity of showing attempts before receiving assistance. This has led to a focus on the original poster's efforts and the need for further elaboration on their approach.

I've decided to give these a different approach. Thanks for the contribution, and sorry for missing the guidelines about posting one's attempts. I might be back to this same thread.

You say you disagree with your textbook on the solutions. Would it be possible for you to elaborate on your approach that leads to these disagreements?
 
It might be just easier, for you as well as me, if I could get some answers and approaches from different people.

I'm afraid that this is not possible without you first showing your efforts at the two questions, according to our posting guidelines;

Homework Help:
On posting questions: Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in our Science Education Zone. This should be done whether or not the problem is part of one's coursework. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work. NOTE: You MUST show that you have attempted to answer your question in order to receive help.

On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given. Under no circumstances should complete solutions be provided to a questioner, whether or not an attempt has been made.
If you could perhaps detail your efforts we could comment on the validity of your solutions.
 
Hi. I'm not going to provide any solution to the qns. However, i can provide you with some hints.

For qn 1) What you could do is to consider the 4 eqns of motion. Form two eqns using one of the eqns and finally, by doing some little manipulation, You should be able to get the ans. Not sure if I'm right but i think the time is 0.822s?

For qn 2) What's the initial velocity? Did the locomotive start from rest or wat?

Perhaps, you could provide us with ur textbook solution and tell us where the prob lies so we can perhaps better analyse the prob.
