A bullet of mass 10 gm moving with a horizontal velocity 100m//s passe

1.	A bullet of mass 10 gm moving with a horizontal velocity 100m//s passes through a wooden block of mass 100 gm. The block is resting on a smooth horizontal floor. After passing through the block the velocity of the bullet is 10m//s. the velocity of the emerging bullet with respect to the block is
Answer» `10 m//s` `9 m//s` `1 m//s` `5 m//s` Solution :`m_(1)u_(1)=m_(1)v_(1)+m_(2)v_(2), v_("rel")=v_(1)-v_(2)`
