    Initial velocity of the object = 31.4 m/s

    Explanation:

    If an object is thrown downward with an initial velocity of v₀ , then the distance it travels is given by s = 4.9 t²+v₀t

    Now an object is thrown downward from a cliff 400 m high and it travels 138.3 m in 3 sec. We need to find initial velocity of the object.

    s = 4.9 t²+v₀t

    138.3 = 4.9 x 3² + v₀ x 3

    3v₀ = 94.2

    v₀ = 31.4 m/s

    Initial velocity of the object = 31.4 m/s
