Ответ:
Option E
A, B, and C are correct
Explanation:
When only the bob is considered as the system, momentum won’t be conserved since velocity after collision will be different from what we initially calculated. Consequently, the value of impulse changes as the change in momentum of the system will be different. Therefore, statements A, B and C are correct.
