We are given that a bullet of mass 10 g moving with a velocity of 400 m/s gets embedded in a freely suspended wooden block of mass 900 g.

Let the final velocity acquired by the block be 'v m/s'.

The mass of the bullet = = 10 g =

= 0.01 kg

The mass of the wooden block = = 900 g =

= 0.9 kg

Also, the initial velocity of the bullet is given by = = 400 m/s

and the initial velocity of the wooden block is given by = = 0 m/s

Now, the momentum conservation of law states that;

Momentum before collision = Momentum after collision

= = 4.4

So, v = 4.4 m/s which means this is the velocity acquired by the block.
