NEET - physics pyq 2024

Q. Two bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity v1 while body B is at rest before collision. The velocity of the system after collision is v2. The ratio v1:v2 is

(NEET-2024)

1. 1 : 2

2. 2 : 1

3. 4 : 1

4. 1 : 4

Before collision

It undergoes completely inelastic collision

Using conservation of linear momentum

Initial momentum = Final momentum

=> mv1 = mv2 + mv2

=> mv1 = 2mv2

V1/v2 = 2/1
