Question

Two acrobats flying through the air grab and hold onto each other in midair as part of a circus act.One acrobat has a mass of 60 kg and has a horizontal velocity of 5 m/s just before the grab.Another acrobat has a mass of 50 kg and has a horizontal velocity of -3 m/s just before the grab.Their horizontal velocity immediately after they grab onto each other is:

    Answer:

    1.36m/s

    Explanation:

    We are given that

    Mass of one acrobat,m_1=60 kg

    Mass of another acrobat,m_2=50 kg

    v_2=-3 m/s

    v_1=5 m/s

    We have to find their  velocity immediately after they grab  onto each other.

    The collision between two acrobat is inelastic

    According to law of conservation of momentum

    m_1v_1+m_2v_2=(m_1+m_2)V

    Substitute the values

    60\times 5+50(-3)=(60+50)V

    300-150=110V

    V=\frac{300-150}{110}=1.36m/s
