Discussion Overview

The discussion revolves around the unit "ni/sec" and its potential meanings or interpretations in the context of speed and distance. Participants explore various possibilities regarding its origin, whether it is a typo, and how it relates to standard units of measurement in physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the source of the problem and suggests that it might be a typo for "mi" (miles) or "m" (meters).
  • Another proposes that "ni/sec" could simply be a miswritten "m/s" (meters per second).
  • Some participants assert that it must be a typo, with one stating that there is no other reasonable explanation.
  • A humorous suggestion is made that "ni" could refer to a fictional unit created by the "knights who say 'ni'."
  • One participant speculates that it could be a case of dyslexia, possibly meaning "in/sec" (inches per second).
  • Another suggests that it might make more sense as "in/hour" (inches per hour).
  • A later reply indicates that if "m/sec" was intended, the problem would be trivial, and it raises the possibility of needing to convert units if "in/sec" was meant.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the meaning of "ni/sec." Multiple competing views remain regarding whether it is a typo, a misinterpretation, or a fictional unit.

Contextual Notes

There are limitations regarding the source of the question, as it was not derived from a textbook, which might have provided clarity on units and conversions. The discussion also reflects uncertainty about the intended unit of measurement.

what is the unit ni/sec??

hi...
someone had ask me what is the unit ni/sec means? and i search through the net but i can't find it. i found something like grams Ni/sec but this Ni=Nickel. and i also came across the below:
"You are traveling at a speed of 15 ni/sec. Your destination is 315 metersaway. How long will it be before you arrive at your destination?"

so can anyone help me and let me know if you know what actually is ni/sec??

many thanks.

1.Where did u see such problem...?If it's a book,doesn't it have a table of units and conversions to SI-mKgs...?
2.It may be a typo in the book.Perhaps it's "mi" apud "miles"...:wink:
3.Rats,i cannot think of another reasonable explanation...

Daniel.
 
Maybe it's just m/s. Sometimes, a written 'm' might be mistaken for an 'ni'.
 
That's a typo. There is no other possible explanation. The question is physics 10 level.

Edit: And you can be pretty sure it isn't a typo for miles! 15 mi/s the person will be there in like .05 seconds!

:smile:
 
It's a new unit created by the knights who say..."ni!" (sorry...heheh)
 
You're right,Cepheid,there are horses which can sustain 15m/s on 315m...

Daniel.
 
It could be someone who had a fit of dyslexia. Perhaps they menat in/sec?
 
It would make much more sense in/hour...Trust me :-p

Daniel.
 
i don't know if it was typo... but i did not get from any textbook, so i could not refer to any tables... i got the question from this link: http://students.resa.net/taylorjfk/teacher/scidepartment/mackson/macksonquiz.htm
the last question...
and haha... 15 miles/sec?? it's like flashing pass...

"6.You are traveling at a speed of 15 ni/sec. Your destination is 315 metersaway. How long will it be before you arrive at your destination? (3 points)"

It would assume that "m/sec" was intended since the distance is given in meters. Of course, that makes the problem trivial. It is possible that "in/sec" was intended and the problem is really to convert from inches to meters (or vice-versa).
