24. 在平面直角坐标系中,抛物线轴的交点分别为原点和点,点在这条抛物线上.

  (1)求点的坐标;

  (2)点在线段上,从点出发向点运动,过点作轴的垂线,与直线交于点,延长到点,使得,以为斜边,在右侧作等腰直角三角形(当点运动时,点、点也随之运动).

     ① 当等腰直角三角形的顶点落在此抛物线上时,求的长;

     ② 若点从点出发向点作匀速运动,速度为每秒1个单位,同时线段上另一个点点出发向点作匀速运动,速度为每秒2个单位(当点到达点时停止运动,点也同时停止运动).过点作轴的垂线,与直线交于点,延长到点,使得,以为斜边,在的左侧作等腰直角三角形(当点运动时,点、点也随之运动).若点运动到秒时,两个等腰直角三角形分别有一条边恰好落在同一条直线上,求此刻的值.
