Sir what is the cutoff marks for bams in government college

[@akki1185]

1:27:01 slide 40 Answer will be 9 As the question said Particle A and B ne collision kiya aur restitution ki value 0 hai toh ye baat clear hai ki unki collision fully inelastic hogi Aur perfectly inelestic collision ke formula ka istemaal krke velocity 9/2 aayegi (inelestic mein dono chipak jaate hai ) Toh ab new body jo banegi A + B uska mass 2m hoga aur C ka already 2m hai TOh ye ab elestic collison ka case hai jisme velocity exchange ho jayegi So answer will be 9 Correct me if i am wrong

1:27:03 HW SLIDE 40 ans is value of x=9 . first value of e is 0 therefore perfect inelastic collision between A and B their speed together will be 9/2 m/s after that as both m and m together 2m move together there will be elastic collision b/w two bodies of same mass therefore velocity will me interchanged therefor C will move with 9/2 m/s

[@PranavNegi-gi6dn]

[@viratmaurya5080]

mera 18 arha hai usme x ki value puchi hai or toh final velocity to 9 aarhi hai 9/2 karenge toh voh 4.5 m/s aagyegii toh 18 hogi tki 2 se divide krne ke badd answer 9m/s aarha hai Agar mein glt hu toh plis sahii bata do.........

[@deepakkushwaha2547]

​@@viratmaurya5080Yes Ur Right

[@sri9043]

​@@viratmaurya5080 First collision is perfectly inelastic so they will combine n the mass will b 2m nd the velocity will b (9m+0m)/(m+m) =9/2 m/s n in the last n final elastic collision the mass r same (2m) so the velocity will interchange so the answer is 9/2 m/s (x/2) .. therefore x=9

e ki value ke sath kya Kiya

[@shauryatripathi8950]

26:30 In elastic collision obviously velocity gets interchanged if mass of both the objects are same. But as the velocity is interchanged the speed will also get interchanged. Because in elastic collision of two bodies of same mass, the speed and the direction of motion gets interchanged, that is why we say that velocity gets interchanged. Hope it helps.......
