A 75 kg skydiver is falling at a speed of 250 km/h when, at a height of 245 m, the parachute is deployed, allowing the skydiver to land at a speed of 4 m/s. Modeling the skydiver as a particle and assuming that the skydiver follows a perfectly vertical trajectory, determine the average force exerted by the parachute from the moment of deployment until landing.
