- Homework Statement:
- A particle of mass m travelling with velocity u collides elastically and head-on with a stationary particle of mass M. Which expression gives the velocity of the particle of mass M after the collision.

- Relevant Equations:
- Momentum=Mass×Velocity

Using principle of conservation of momentum:

m×u=m×v1 + M×v2

Where m=mass of moving particle in the beginning

u=Initial velocity of particle m

v1= final velocity of particle m

v2=velocity of object M

m×u-(mv1)=Mv2

(mu-mv1)÷M=v2

My answer is this (mu-mv1)÷M

However, it is nowhere close to the correct answer. Kindly tell where I am going wrong in the calculation.

m×u=m×v1 + M×v2

Where m=mass of moving particle in the beginning

u=Initial velocity of particle m

v1= final velocity of particle m

v2=velocity of object M

m×u-(mv1)=Mv2

(mu-mv1)÷M=v2

My answer is this (mu-mv1)÷M

However, it is nowhere close to the correct answer. Kindly tell where I am going wrong in the calculation.
