SUMMARY
The discussion centers on calculating the drag coefficient (D) required for a man weighing 50.0 kg to achieve a terminal velocity of 42 m/s. The user applied the formula V = (mg/D)^(1/2) and derived D = 0.28 kg/m. However, the textbook states the answer is 44 kg/m, leading to confusion about the correctness of the user's calculation versus the book's answer. The user's calculation is confirmed to satisfy the equation, indicating a potential error in the textbook.
