Q13 (7.5 points): A man with a parachute jumps out of a frozen helicopter at height . During the fall, the man's drag coefficient is (with closed parachute) and (with open parachute) and air resistance is taken as proportional to velocity. The total weight of the man and his parachute is . Take the initial velocity when he jumped to be zero. Gravitational constant is . The man opens the parachute time after he jumps. Please find the total falling time and the speed he hits the group. Can you adjust the to enable the quickest fall and lightest hit on the ground?...
