A kangaroo wishes to jump over a 1.0-m-high barrier that is 3.0 m away. On this occasion the kangaroo jumped with a speed of 11 m/s with respect to the ground, it was observed that the maximum height it reached on its way was 1.5 m and it barely managed to clear the barrier passing to the other side. How far did the kangaroo fall from its initial position if the starting point and ending point are at the same height?
