a body of masses 2kg,initially moving with
a velocity of 10m/s collides with another body of masses 5kg at rest .after collision velocity of first body becomes 1m/s.Find velocity of the second body.

Open in App

Solution

The information provided in the question is as follows:

Mass of first body,m₁ 2 kg

Mass of second body, m₂ 5 kg

Initial velocity of first body, v₁ 10 m/s

Initial velocity of second body v₂ 0

Final velocity of first body, v₁' 1 m/s

From conservation of momentum,
Initial momentum = Final momentum
$\Rightarrow m_{1} v_{1} + m_{2} v_{2} = m_{1} v_{1}' + m_{2} v_{2}' \Rightarrow 2 \times 10 + 0 = 2 \times 1 + 5 \times v_{2}' \Rightarrow v_{2}' = \frac{20 - 2}{5} = 3.6 m/s$
