When you drop an object from a height of 17m, it hits the ground
1.86 seconds later, with a speed of 18.25 m/s.
That's the same time it takes our daredevil to hit the water. During
the 1.86 seconds that he's falling and yelling, he's traveling 4m/s
horizontally, and lands 7.45 meters from the bottom of the cliff.
Let's hope the water begins closer to the cliff than that.
