Question

An Olympic diver is on a diving platform 1.45 m above the water. To start her dive, she runs off of the platform with a speed of 4.01 m/s in the horizontal direction. What is the diver's speed just before she enters the water?

00:01 All right, so let's say we have an olympic diver running off of a diving board with a speed of, let's see, 4 .01 meters per second, horizontally, and the diving board is 1 .45 meters above water.
00:19 So we're going to know what speed do they hit the ground.
00:21 So what will have is their final speed, we'll call vf squared, minus their initial speed, squared, over twice the height they fell from, should be equal to g...
