4. Our second-to-last parachuting idiot (whose mass is 50kg) of the semester has jumped from a height of 20,000m. Her parachute is broken, obviously. Ignoring air resistance, how long will it take her to reach the Earth? At what speed would she hit the ground? b. She is subject to a linear air resistance term and a quadratic air resistance term. Which of these terms is likely to dominate? Why? Including air resistance, at what velocity will she strike the Earth? (Assume the coefficient to be 0.3Ns for quadratic or 0.3 N s/m for linear, depending on your answer for part b.) C.
