Answer 1

7)

The real reason for the difference in the change in momentum and impulse applied is that the real systems have inelastic collisions and have loss of energy instead of elastic collisions. Hence when impulse if applied to any system some amount of energy is lost in either deformation of the object or in the frictional energy hence the system doesnt have same amount of energy hence having the difference in momentum changed and impulse applied.

8)

Since the value of impulse provided to the system is almost half of the change in momentum in case A and C hence the the error is too large to be neglected hence the impulse momentum theorem cannot be verified based on cases A and C. The difference between impulse provided in Case B is very small and almost negligible and in case B the impulse momentum theorem is verified.
