    Free fall motion is a uniformly accelerated linear motion with zero initial velocity;

    The ratio of the displacements passed by a uniform acceleration linear motion with zero initial velocity at a continuous equal interval of time x1 : x2 : x3 : ....=1：3：5：…；Hence h1

    h3=1 5

    h3 = 5h1 = 5;

    So choose C

    C is composed of s = 1 2at2

    It can be seen that the total displacement ratio of t 2t and 3t is 1:4:9 respectively, so the ratio of t in each section is 1:3:5, and the answer is selected C
