    Answer:

    The displacement of the volleyball is 2.62 m

    Explanation:

    Given;

    initial velocity of the volleyball, u = 7.5 m/s

    final velocity of the volleyball, v = 2.2 m/s

    displacement of the volleyball, d = ?

    Apply the following kinematic equation;

    v² = u² – 2gd

    2gd = u² – v²

    d = \frac{u^{2}-v^{2} }{2g}\\\\d = \frac{7.5^{2}-2.2^{2} }{2*9.8}\\\\d = 2.62 \ m

    Therefore, the displacement of the volleyball is 2.62 m
