When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 852 N and the drag force has a magnitude of 1012 N. The mass of the sky diver is 86.9 kg. Take upward to be the positive direction. What is his acceleration, including sign?
