A10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 34 m/s when a 60 kg skydiver drops out by releasing his grip on the glider. what is the gliders speed just after the skydiver lets go? express your answer to two significant figures and include the appropriate units.
