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 942 N and the drag force has a magnitude of 1045 N. The mass of the sky diver is 96.1 kg. What are the magnitude and direction of his acceleration?

Net force= mass*acceleration
using upward as the + direction,
1045-942= mass*a
