Question

a bullet of mass 10 gram moving with a velocity of 400 metre per second gets embedded in a freely suspended wooden block of mass 900 gram what is the velocity acquired by the block

Answer 1

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