Answer 2

Explanation:

1. momentum
2. change in momentum...mv-mu...m(v-u)...1500(72-36)...1500×36...54000kg m/ s
3. due to a greater change in momentum as inside bus, we were in motion but as soon as we jump out of it we came into rest and a large change in momentum caused a larger damage.
4. using s=ut +1/2 at^2...a= 2m/s^2 using f=ma, f=7000×2=14000N
5. usingf=ma. .f=1×1=1N
6. using law of conservation of momentum, m1u1=-m2v2 recoil velocity of gun...6m/s

hope it helps...
