Before Collision After collision
A B → A B
100 g 200g → 100g 200g
2m/s 1m/s v=?
Let the 100 g and 200 g objects be A and B as shown in above figure.
Initial momentum of A=×2=
Initial momentum of B=×1=
∴ Total momentum of A and B before collision
=0.2+0.2=
Let the velocity of A after collision =v
∴ Momentum of A after collision =×v=0.1v
Also, momentum of B after collision=×1.67=
∴ Total momentum of A and B after collision
=0.1×v+0.334
Using the law of conservation of momentum, momentum of A and B after collision = momentum of A and B before collision
⇒0.1×v+0.334=0.4
⇒0.1×v=0.4−0.334
⇒v= =
