Question

A skydiver has a mass of 72 kg and a weight of 706 N. He is descending on a parachute and his speed is still increasing at 1.2 m/s².

What is the magnitude and direction of the net force on the skydiver? Explain.

What is the magnitude and direction of the force that the parachute harness exerts on the skydiver? Explain.

Answer 1

Answer #1

There are two forces acting on the skydiver: 1) weight (w) in downward direction and 2) air resistance due to parachute in the upward direction

Since there is an acceleration of 1.2 m/s² in downward direction. net force is in downward direction.

F_net = ma = 72*1.2 = 86.4 N

F_net = w - F_para

F_para = w - F_net = 706 - 86.4 = 619.6 N

parachute harness exerts force in the upward direction on the skydiver

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 964 N and the drag force has a magnitude of 1022 N. The mass of the sky diver is 98.4 kg. Take upward to be the positive direction. What is his acceleration, including sign?
