An experiment is performed aboard the International Space Station to verify that linear momentum is conserved during collisions

Anni [7]

Answer:

$v=15.9554\ m.s^{-1}$

Explanation:

Given:

mass of the honey drop 1, $m_1=35.5\times 10^{-3}\ kg$

velocity of the honey drop 1, $v_1=13.1\ m.s^{-1}$

mass of the honey drop 2, $m_1=52.3\times 10^{-3}\ kg$

velocity of the honey drop 2, $v_2=14.5\ m.s^{-1}$

mass of the honey drop 3, $m_1=75.7\times 10^{-3}\ kg$

velocity of the honey drop 3, $v_3=18.3\ m.s^{-1}$

<em>In ISS there is zero gravity an the collision is completely inelastic.</em>

<u>So, applying the law of conservation of momentum:</u>

$m_1.v_1+m_2.v_2+m_3.v_3=(m_1+m_2+m_3).v$

$35.5\times 10^{-3}\times 13.1+52.3\times 10^{-3}\times 14.5+75.7\times 10^{-3}\times 18.3=(35.5+52.3+75.7)\times 10^{-3}\times v$

$v=15.9554\ m.s^{-1}$
