In an inelastic collision, a steel ball of mass 200 g was hit hard into a large ball of dough of mass 700 g. The velocity of the steel ball

Question

In an inelastic collision, a steel ball of mass 200 g was hit hard into a large ball of dough of mass 700 g. The velocity of the steel ball was 25 m/s. After the collision, the steel ball was stuck in the dough, and this combined system rolled for some time. What was the velocity of the system of the steel ball and dough after the collision?A) 5.6 m/sB) 7.5 m/sC) 8.8 m/sD) 11.1 m/s

    Answer:

    Velocity after collision will be 5.56 m/sec

    So option (a) will be correct answer

    Explanation:

    Mass of steel ball m_1=200gram=0.2kg

    Speed of steel ball before collision v_1=25m/sec

    Mass of large ball m_2=700gram=0.7kg

    Velocity of large ball v_2=0m/sec

    According to conservation of momentum

    m_1v_1+m_2v_2=(m_1+m_2)v

    0.2\times 25+0.7\times 0=(0.7+0.2)v

    v=5.56m/sec

    So velocity after collision will be 5.56 m/sec

    So option (a) will be correct answer
