the ans is C: both energy and momentum is conserved since in a elastic collision two bodies coming frm some particular distances after collision they return to there original hieght.

C is true, 'coz a perfectly elastic collision is defined as a collision in which both energy and momentum are conserved.

C: perfectly elastic is basic theoretically ideal situation, where no energy or momentum is lost. This is the correct answer, while it has only theoretical relevance.

Use communique of momentum to do this concern... purely comprehend that with a wonderfully inelastic collision the velocities of the two balls stands out as the comparable as they stick jointly. Hit me up on aim in case you opt for some greater help...Steveobob867
