MCQ
Consider $a$ one-dimensional collision that involves $a$ body of mass $m_1$ originally moving in the positive $x$ direction with speed $v_0$ colliding with a second body of mass $m_2$ originally at rest. The collision could be completely inelastic, with the two bodies sticking together, completely elastic, or somewhere in between. After the collision, $m_1$ moves with velocity $v_1 $ while $m_2$ moves with velocity $v_2$.

$(A)$ $If \,m_1 > m_2$,

$(B)$ $If\, m_1 < m_2$,

  • A
    $ -v_0 < v_1 < 0$ $;$  $ -v_0 < v_1 < 0$
  • B
    $v_0 < v_1 < 2v_0$ $;$ $0 < v_1 < v_0$
  • C
    $0 < v_1 < 2v_0$ $;$ $0 < v_1 < v_0/2$
  • ✓
    $0 < v_1 < v_0$ $;$  $-v_0 < v_1 < v_0/2$
✓

Answer

Correct option: D.
$0 < v_1 < v_0$ $;$  $-v_0 < v_1 < v_0/2$
