Question

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 904 N and the drag force has a magnitude of 1003 N. The mass of the sky diver is 92.2 kg. Take upward to be the positive direction. What is his acceleration, including sign?

Expert Solution

Step 1

$Weight of sky diver (w) = 904 N (a c t i n g d o w n w a r d s) Magnitude of drag force (f) = 1003 N Since the drag force acts in the opposite direction to that of motion, thus drag force is acting in the upwards direction . mass of sky diver (m) = 92.2 k g$
