Today we are going to solve a very interesting JEE Physics problem which you can expect in exams like JEE Mains, BITSAT, JEE Advanced etc.
The problem states:-
A boy of mass 50 kg is standing at one end of a 9.0 m long boat of mass 100 kg that is floating motionless on a calm lake. The boy walks to the other end of the boat and stops there. The boat also moves and finally stops due to water resistance. If force of water resistance is proportional to velocity of the boat relative to water. what is the magnitude of the net displacement s of the boat?
(a) s = 0.0 m
(b) s = 3.0 m
(c) s less than 3.0 m
(d) s greater than 3.0 m
Now unlike other man-boat problems where we easily find the displacement of the boat by conservation of momentum, we have another factor here ie. water resistance.
This water resistance changes the entire story and will try to confuse you.
But if you are really a good JEE aspirant and have done preparation to a decent level in physics, you will be able to find the solution correctly.
Do give this JEE physics question an attempt and if you fail to find the correct solution, go through the entire solution sincerely.
The concept used to solve this question is change is momentum will be zero in both cases because finally both the man and boat come to a rest.
Check out the complete solution and learn the concepts so that you can apply them during your JEE tests and exam.

Sir Aapke sochne ka tarika vaki sabhi teachers se bhut different hai ,aapke sabhi videos ko dekhta hu toh ek khushi milti hai aur lagta hai ki kuch new chiz sikhi 🙏🏻🙏🏻🙏🏻❤❤ thank you so much sir for all efforts ❤️🔥

My thought was ki jab boat friction ki vajah se peechhe move karegi aur resistance force aage lagega to fir water molecules aage displacement karenge aur net displacement hame boat ki displacement minus water ki displacement se mil jayega jiski value 3meter se kam hogi so I gave answer less than 3meter ❤ But now I understood sir

Sir , i always get around 70 to 75 peacefully, im aiming to get 90+ in april attempt, this is the third time im requesting guruji, NMS sir to upload complete syllabus marathons of duration 1:30:00 to 2:00:00 . This might be in need only for me. But upload two such videos, if they dont perform well , you can stop it there itself sir. Please sir , i request NMS sir to take physics question marathons sessions. I am regretting that i found your channel so late. Your problem solving approach always amazes me, Im a fellow physics enthusiast (still a learner) but i aspire to be a quality teacher who knows his stuff like you.

NMS sir if we consider boy +boat system then f=ma implies kv=mvdv/dx implies kdx=mdv integreating both side since dv=0 dx=0 note m=150

Sir, I have a doubt regarding velocity of water. will water also have a velocity. Sir in ques there was written calm lake , sir is the water of lake calm through out the motion or it is there we aren't considering it to affect the motion or any thing else . Sir pls clarify my doubt.🙏🙏

Sir I have one doubt in one concept based on kinematics in problems like 3 people moving towards each other in a triangle or any polygon in which we find different things like time acceleration etc but I am unable to find distance coverd by each particle in one revolution can u plsss helpppppp plsss sirrrr

Distance equals their speed times time of collision or meeting at geometric centre
