A skydiver has a mass of 55 kg (including the parachute). She opens the parachute when she reaches a velocity of 22.0 m/s [down]. The parachute exerts an upward force of 866 N.

(a) Draw a free-body diagram of the forces acting on the skydiver once the parachute has opened.

(b) What is the acceleration of the skydiver after the chute opens?

(c) What is her velocity after an additional 2.0 seconds have passed?
