हिन्दीA loaded truck of mass \( 4000 \text{ kg} \) and a light car of mass \( 1000 \text{ kg} \) have the same linear momentum. If the speed of the light car is \( 24 \text{ m s}^{-1} \), the speed of the loaded truck is:
Correct answer · Option 4
\( 6 \text{ m s}^{-1} \)
Explanation
Since momentum \( p = mv \) is equal for both vehicles, \( m_1 v_1 = m_2 v_2 \implies 4000 \times v_1 = 1000 \times 24 \implies v_1 = 6 \text{ m s}^{-1} \).
