    A rock is dropped from a sea cliff and hits the water 3.2s later. How high is the cliff?

    t = sqrt (2y/g)

    3.2 = sqrt (2y/9.81)

    y = 50.23 m

    How long would it take sound to travel the same distance?

    t = 50.23 / 343 m/s

    t = 0.15 s

    How long would it take light to travel this distance?

    t = 50.23 / 299 792 458 m / s

    t = 1.68x10^-7 s
