Following is the text part of the solution. Please see the attached file for complete solution. Equations, diagrams, graphs and special characters will not appear correctly here.
==============================
Air resistance F is proportional to the square of the velocity and is opposite to the direction of motion.
F = - k v2, where k is a constant. (- sign is to indicate the direction)
During the flight up, forces are mg and F ...
