Answer:0.25 kg-m/s
Explanation:
Given
mass of blob 
initial velocity 
time of collision 
we know Impulse is equal to change in momentum
initial momentum 

Final momentum 
as final velocity is zero
Impulse 


Really long we’ll not long but far in distance
Practically yes
So
If mass is more output may come less so it affects the efficiency practically
But thepritically it doesn't
