... 3. An 85 kg skydiver is accelerating through the air, which is exerting a force of air resistance of 250 Newtons. What is the acceleration of the skydiver? Weight of skydiver = mg = 85 kg x 9.8 m/s2 = 833 Newtons. Net Force = 833 N + - 250 N = 583 Newtons. acceleration = Fnet / mass = 583 N / 85 kg ...
