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]

  • Screenshot of a multiple-choice physics question reading: To break the world record for breaking cement blocks, this man produced 950 Newtons of force in 0.12 seconds over the blocks. How much impulse did the blocks experience? A Choose dropdown is below.

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.
