Exactly the same situation as the baseball rolling off the desk, only with different numbers.
Distance falling from rest = (1/2) · (g) · (T²)
Janet fell from rest and landed in the water 2.1 sec later.
How high did she fall from ?
Distance = (1/2) · (9.8 m/s²) · (2.1 sec)²
Distance = (4.9 m/s²) · (4.41 s²)
<em>Distance = 21.61 meters</em> (HIGH platform. About 71 feet ! ! )
She didn't just roll off the edge of the platform.
She shot out from it horizontally, at 2.46 m/s.
She kept moving horizontally at 2.46 m/s all the way down.
How far was she from the tower when she went <em>SPLAT</em> at the bottom ?
Distance = (speed) · (time)
Distance = (2.46 m/s) · (2.1 sec)
<em>Distance = 5.17 meters</em>
<em>(That's 17 feet from the tower ! I sure hope they put the pool that far out.)</em>
