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)

Distance = 21.61 meters (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 SPLAT at the bottom ?

Distance = (speed) · (time)

Distance = (2.46 m/s) · (2.1 sec)

Distance = 5.17 meters

(That's 17 feet from the tower ! I sure hope they put the pool that far out.)
