There are four characteristics of a state. population,government,sovereignty,and territory.
Answer= 8m/s
Because total Momentum before= total momentum after
Momentum before (p=mu)
p=(4)(12)= 48
p=2(0)=0
So total momentum before=48
Momentum after (p=mu)
Masses combined —2+4=6kg
p=6u
Mb=Ma
48=6u
u=8m/s

I believe the answer is H for when you bounce it, it has stress when it hits the floor and then goes up giving it kinetic
