Final answer:
To convert 26 m/s to km/h, we multiply by 3.6, resulting in a terminal speed of 93.6 km/h for the ball. However, this result is not listed in the provided options, indicating a potential error in the question or options.
Step-by-step explanation:
The question asks us to convert the terminal speed of a ball from meters per second (m/s) to kilometers per hour (km/h). The given terminal speed is 26 m/s. To convert m/s to km/h, we multiply by a conversion factor of 3.6 (since 1 m/s equals 3.6 km/h).
Therefore, the calculation would be 26 m/s × 3.6 = 93.6 km/h.
However, as this answer is not amongst the provided options, it seems there might be an error in the question or the options given. It is essential to recheck the original problem or the provided options for any mistakes.
