Can anyone explain this why answer of question no . 84 is C. Momentum should be conserved in inelastic as well as elastic collision.

K.E will be lost after collision 💥 in the form of Sound Energy, Deformation Energy, Heat Energy; K.E not conserved. Momentum is conserved 100% only in an isolated system.

Momentum hamesha conserve hota hai, chahe collision elastic ho ya inelastic, kyunki is par koi external force nahi lagti. Kinetic Energy sirf elastic collisions me conserve hoti hai; inelastic me iska kuch hissa heat, sound, ya deformation me convert ho kar lose ho jaata hay ...So "A" is the right option

bro according to my thinking it is correct because car is as we know inelastic body there will be deformation in it's shape due to which momentum and K.E would not be conserved
