Engineering Problem, Newtons Law based, Any help would be great

Click For Summary

Discussion Overview

The discussion revolves around an engineering problem related to Newton's laws, specifically focusing on a question that involves calculations based on a velocity-time graph. The scope includes practical application in an engineering apprenticeship context and addresses specific parts of the problem that the original poster finds challenging.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • The original poster, Mike, presents a problem involving the calculation of distance (S) using the formula S = (V.T)/2, where he has determined S to be 100 and T to be 20 m/s, leading to a calculated velocity (V) of 10 m/s.
  • Mike expresses difficulty in solving parts B and C of the problem and seeks assistance from the forum members.
  • Another participant questions the definition of "T," seeking clarification on whether it represents time or velocity, indicating some confusion regarding the units used.
  • Mike later clarifies that "T" is indeed time and acknowledges a typographical error in his previous post.
  • Mike indicates that he believes he has made progress on the problem and expresses willingness to share his solution once completed.

Areas of Agreement / Disagreement

The discussion shows some initial confusion regarding the variables used in the problem, particularly the interpretation of "T." However, there is no explicit consensus on the correctness of Mike's calculations or the approach to solving parts B and C, as the discussion remains open-ended.

Contextual Notes

There are unresolved aspects regarding the clarity of the problem statement and the specific requirements for parts B and C, which may affect the understanding of the overall task.

Who May Find This Useful

This discussion may be useful for individuals engaged in engineering apprenticeships or those studying Newton's laws and related calculations in practical contexts.

Hi guys.

This is my first post.

I am currently on an engineering apprenticeship and its mostly practical but i have been given a Newtons law question which i am finding very hard.

I have attempted it but still come up stuck.

I have attached the question with the drawing.

I have answered part a.

With S= (V.T)/2
S was 100 (area under the Velocity / time Graph)

T was 20 m/s

So that gave (S)100 = V(?) x (T)20 / 2

So V = 10 m/s

Now I'm really stumped on B and C.

Any help would be Great.

And now I've found this site i hope to give a lot of help back as i have nearly finished my partisanship.

Mike

Welcome to the PF, Mike. I've moved your post to the Homework Help section of the PF. Even though it is for an apprenticeship, this kind of post still qualifies as homework/coursework-like, and needs to be kept in the Homework Help forums.

I'm a bit confused by the work you've done so far. What is "T"? Is it a velocity, with units of m/s?
 
Thanks for moving it (sorry i put it in the wrong place), i had considered putting it in here but i thought engineering.

And T is time and i have put M/ in extra (dam) i would edit that but carnt (think cos its been moved).

As for doing it i think I've cracked it, so will post the answer tomorrow (if its wanted)

Yes, please post the answer when you get it. Glad that you're figuring it out.
