There is only a negative acceleration if you assume positive is to the right. If you frame positive 'x' to be left, you don't get a negative acceleration.
@@Daisy-i9h9t bcoz block has moved from point A to point B with some sort of acceleration in x direction. That's why we are finding ax value at point B.
You took 11 minutes to solve it, however, you know each step and do it with no thinking. Does it make any sense to come in fe exam with 3 minutes to be solved ?
That is a good approach actually! Always mark the difficult and long questions and return to them at the end. Being organized and having an exam strategy will go such a long way in passing the FE.
Thanks for the video. But there is no way that this kind of lengthily problem would show on the FE exam. FE exam problems are put to be solved in less than 3 minutes.
This could easily be on the FE. If you know your way around kinematics, this is a simple problem. I'd imagine there could be a similar problem in the statics section as well.
I solved this one using the Principle of Work and Energy T2 + V2 = T1 + V1 + U1->2, where U1->2 is the friction force (negative) opposing energy.
Of course we need more problems
Can you make videos about each section in fe with like 8-10 problems
Thank you for your detailed explanation
Thank you for watching, Saud! We're so glad that you found it helpful!
Thank you for your helpful videos, can you please make a video about construction and how to calculate productivity?
I think we should solve this problem by work=kinematic energy, since we are getting a negative acceleration to avoid conclusion of the vector

Hi Kenza, Could you please tell me why Max (mass x ax), I never saw tis equation before. Thanks!
F= ma newton second law

why can't i use 3/4/5 triangle instead of finding the actual angle? i dont get the same answer.
This problem looks and is very hard.
Thank you
Thank you for watching Brian! We're so happy you find our videos helpful. Good luck with your FE. 😊
Hi, are all your sample problems came out on your exam?
Hello, some of them are and some of them are just problems I studied to help me prepare for the exam.
@@Genieprep Thank you.

Good videos, i would work on the intro music tho xD
Really thanks very much, U make the life much easier. Your videos very helpful. Keep going. Thanks again 😘😘
Best thing you can do on the FE if you get this question is skip it IMO. Takes way too long to solve. Good luck!
