A 10-m-long glider with a mass of 680kg (including the passengers) is gliding horizontally through the air at 26m/s when a 60kg skydiver drops out by releasing his grip on the glider.

What is the glider's speed just after the skydiver lets go?

If steel is more dense that lake water, why can a boat float
