1.	msndreyfriction be neglected, the velocity of the system must be
Answer» Mass of bullet = a Mass of wood = c Velocity of bullet = b. Initial momentum of the bullet = ab Initial momentum of the wood = c×0 = 0 (because the wood was at rest) Final mass of the system = a + c (because bullet goes inside the wood) Let the velocity of the system = v We know that Initial momentum = final momentum Initial Momentum of bullet + initial momentum of the wood = final momentum of the system ab + 0 = (a + c)v =>v = ab/(a + c)

Answer»

Mass of bullet = a

Mass of wood = c

Velocity of bullet = b.

Initial momentum of the bullet = ab

Initial momentum of the wood = c×0 = 0 (because the wood was at rest)

Final mass of the system = a + c (because bullet goes inside the wood)

Let the velocity of the system = v

We know that

Initial momentum = final momentum

Initial Momentum of bullet + initial momentum of the wood = final momentum of the system

ab + 0 = (a + c)v

=>v = ab/(a + c)
