Easy Question That I need help with

  1. Oct 30, 2006 #1
    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
