Final answer:
The terminal velocity of a skydiver in a spread-eagle position is approximately 200 km/h, which is the closest value from the given options. In a headfirst position, this velocity can be as high as about 350 km/h.
Step-by-step explanation:
The terminal velocity of a skydiver depends on their mass, the position they hold during freefall, and their frontal area. For a skydiver falling in a pike (head first) position, the terminal velocity is quite high; for a person with a mass of 75 kg, this velocity can be about 350 km/h. However, if they adopt a spread-eagle position, the terminal velocity may decrease to about 200 km/h due to the increase in frontal area, which increases air resistance.
Since none of the options provided exactly match 200 km/h or 350 km/h, the most accurate answer from the selections is 200 km/h for a skydiver in a spread-eagle position. For rigorous calculations, assumptions about the skydiver's frontal area would be necessary, along with the application of appropriate physics formulas to determine the exact value of terminal velocity.
