Air resistance (the resistance to motion in air) is often ignored when modeling systems on Earth. However, when objects are falling at high velocities through the atmosphere, air resistance cannot be ignored. You convince your 60-kg friend to jump out of a plane and take some measurements on herself.

(a) When she first jumps out of the plane, her velocity is so small that air resistance is negligible. At this point, she falls with an acceleration of 9.81 m/s². Sketch a graph of force from air resistance versus acceleration that includes the time period from when your friend leaves the plane until she reaches a constant terminal velocity.

(b) After about 12 s, she reached a constant terminal velocity. (She can tell this because her accelerometer now reads zero.) What is the force from air resistance at this time?
