    I am repeating my As level.

    Oh ma'am ! Sorry. :)

    As physics p1 MCQS YEARLY ONLY.

    Coz I showed the steps in 1st post of that doubt, so I just showed that C and D is inelastic lol..

    How m I wrong ._. I mean I showed all steps, I didn't skipped a single step ._.

    I showed all steps ._. C is inelastic coz it is moving in one direction, and D is inelastic coz its stick ._. So for inelastic either speed is in same dirctn or it is stick and hence C and D are inelastic Now say :/

    Sir, This year papers were easy only few questions were tricky... But due to lack of time I couldn't prepare for chem, M1, Eng and comp... :( Physics me to A ayega and P1 bhi acha gaya tha ;) Oh thanks a lot :) Satisfied :)

    Well see this :¬ Pi = pf right ? so Pi = 2mu - mu = mu and for option A -2mu/3 + 5mu/3 = mu so momentum is conserved. Pi = Pf for B -2mu/6 + 2mu/3 = 4mu/6 so momentum is not conserved Pi ≠ Pf for C 2mu/6 + 2mu/3 = mu so momentum is conserved Pi =Pf for D (2m + m) * u/3 = mu so momentum is...

    Lol.. I wanna know... on what basis you said my answer is invalid ? o_O :eek:

    Why ? For momentum to be conserved Pi = Pf so Pi = 2mu - mu = mu so Pf for A,C,D = mu hence they are conserved, but C and D are inelastic collision so A... How does it not make sense ?

    I think this is a long method...

    mehria I want your opinion !

    In question A,C and D are conserved as Pi = Pf But C and D are inelastic collision, so answer is A :)
