4. A skydiver is falling with speed v0 through the air. At that moment (time t = 0), she opens her parachute and experiences the force of air resistance whose strength is given by the equation F = kv, in which k is a proportionality constant and v is her descent speed. The total mass of the skydiver and equipment is m. Assume that g is constant throughout her descent. (a) Draw and label all the forces acting on the skydiver after her parachute opens. (b) Determine the skydiver’s acceleration in terms of m, v, k, and g. (c) Determine the skydiver’s terminal speed (that is, the eventual constant speed of descent). (d) Sketch a graph of v as a function of time, being sure to label important values on the vertical axis.
