A 85 kg skydiver parachutes from a stationary helicopter at a height of 1,200 m above the ground. After the skydiver reaches a predetermined speed, the parachute opens, slowing the skydiver down. With the parachute open, the skydiver reaches a terminal velocity of 3.5 m/s. Calculate the work done by air resistance during the descent from the height of the helicopter to the ground.
