Homework Help Overview

The discussion revolves around calculating impulse given a force of 950 N applied over a time interval of 0.12 seconds. The original poster attempts to apply the impulse formula J=FT but encounters a discrepancy with the answer choices provided.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculation of impulse and question the units of the result. There is also a consideration of the wording of the problem, with some suggesting that the force may not be constant over the time interval.

Discussion Status

The discussion is ongoing, with participants raising questions about the interpretation of the problem and the validity of the calculated impulse. Some guidance has been offered regarding the need for clarification on units and answer choices.

Contextual Notes

There is uncertainty regarding the nature of the force application and how it relates to the impulse calculation, as well as a lack of clarity in the problem statement itself.

Homework Statement



The question is asking me about how much impulse is applied. I would attach a picture but I honestly do not know how.

Force=950 N

Time=0.12 seconds

Homework Equations


J=FT

The Attempt at a Solution


J=(950)(0.12)=114. The problem with this is that there is not an answer choice for 114 so obviously I have done something incorrect. Help please[/B]

You asked me to help, this answer seems to be correct to me, but as I'm just a high school student, you might want to wait for a professional to look at this, just to be sure.

114 in what units? And what are the answer choices?
 
The wording is strange. I would have expected to be told a certain force was produced for a time against the blocks, not in a time over the blocks.
So, maybe it means the force peaked at 950 N at the end of 0.12 s, but then you'd have to make some assumption about how the force grew over that time. Seems very unlikely.

These are the answer choices.
