Two bodies AA and BB of same mass undergo completely inelastic one dimensional collision. The body AA moves with velocity v1v_1 while body BB is at rest before collision. The velocity of the system after collision is v2v_2. The ratio v1:v2v_1: v_2 isTwo bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity

Options

  1. A2:1
  2. B4:1
  3. C1:4
  4. D1:2

Correct answer

A. 2:1

Step-by-step solution

Two bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity
It undergoes completely inelastic collision Using conservation of linear momentum Initial momentum = Final momentum ⇒mv1=mv2+mv2⇒mv1=2mv2⇒v1v2=21\begin{aligned} & \Rightarrow m v_1=m v_2+m v_2 \\ & \Rightarrow m v_1=2 m v_2 \\ & \Rightarrow \frac{v_1}{v_2}=\frac{2}{1} \end{aligned}
