    Answer:

    14.7 m/sec.

    Explanation:

    We will go about using the mathematical formula,

    Vf – Vo = gT.

    To break it down,

    Vf = Velocity of the apple just before hitting the ground.  

    Vo = Initial velocity of apple = 0  

    T = Time for apple to hit the ground = 1.5 sec  

    g = Acceleration due to gravity = 9.8 m/sec^2

    We then need to substitute appropriate values,

    Vf – 0 = 9.8(1.5)  

    Vf = 14.7 m/sec.
