Impulse Question

Tags:
  1. Nov 22, 2015 #1
    1. The problem statement, all variables and given/known data

    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
    2. Relevant equations
    J=FT

    3. 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

    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.
