Homework Help Overview

The discussion revolves around calculating the impulse of a collision, specifically focusing on the relationship between average force, collision time, and the units of impulse. Participants are exploring the correct interpretation of the units involved in the calculation.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the formula for impulse, with one suggesting the use of the equation Impulse = Force x Time. There is confusion regarding the desired units for the answer, with questions raised about the appropriateness of Joules-seconds versus Newton-seconds.

Discussion Status

The discussion is active, with participants questioning the original poster's unit preference and offering differing opinions on how to approach the calculation. Some participants suggest that the unit issue may be a typographical error, while others seek clarification on the context of the problem.

Contextual Notes

There is mention of specific values for average force and collision time, but the original poster's requirement for the unit of impulse remains unclear, leading to further questioning of assumptions.

I was to calculate the impulse of a collision. I was given the Average force in Newton, and the collison time in seconds. I need the answer to be in Joules - Seconds and not in Newton - Seconds. I used the equation Impulse = Force x Time. I am have a tremendous brain fart. Can you help?

I don't think you want your answer to be in Joule-seconds, since that's not the unit of momentum...

What's the context?
 
A collision occurs w/ a time of impact is 35.1 milliseconds and the average force is 509.79 N. What is the impulse (in Joules-Seconds)?
 
I would just go with F*t and ignore that part. It may just be a typo
