    Given that:

    Ball dropped from a bridge at the rate of 3 seconds

    Determine the height of fall (S) = ?

    As we know that, S = ut + 1/2 * a. t²

    u = initial velocity = 0

    a = g = 9.81 m/s (since free fall)

    S = 0 + 1/2 * 9.81 * 3²

    S = 44.145 m

    44.145 m far is the bridge from water
