    Impulse
AI Thread Summary
The discussion revolves around calculating impulse using the formula J=FT, where a force of 950 N is applied over 0.12 seconds. The initial calculation yields an impulse of 114, but this result does not match any provided answer choices, leading to confusion. Participants question the units of the impulse and the clarity of the problem statement, suggesting that the wording may imply a peak force rather than a constant force. There is uncertainty regarding the interpretation of the problem, particularly how the force is applied over time. Clarification on the answer choices and the units of measurement is needed for a definitive solution.

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.

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
