Question

Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.27 m/s upwards. Use energy conservation to find his speed when he strikes the water.

Answer 1

They should have told you the springboard height above the water. For Olympic competition, it is 3.0 meters.

That height, the initial speed and conservation of energy should tell you what the water impact speed is.

Answer 2

1.5
