When a parachute opens the air exerts a large drag force on, Ask an Expert

Academics

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 998 N and the drag force has a magnitude of 1046 N. The mass of the sky diver is 102 kg. Take upward to be the positive direction. What is his acceleration, including sign?
