Explanation / Answer

So first I will find the speed of the block directly after its interaction with the bullet. I will use conservation of energy.

PE=KE
mgh=(1/2)mv.

v2=2gh

v2=2(9.8)(0.0045)= 0.0882

vblock =0.296 m/s

Now we can implement conservation of momentum

p1=p2

mbulletvbullet1=mbulletvbullet2+mblockvblock

(0.005)(440)=(0.005)vbullet2+2(0.296)

vbullet2=321.2 m/s
