RMF factor calculation: Suppose you want a 7 lb robot to have a speed of 5 ft/sec and accelerate at 3 ft/sec^2. Using the formula mass x acceleration x velocity (2 x Pi), what is approx RMF?

Explanation:
The calculation uses RMF as a rotational-style factor by converting linear quantities with the factor 1/(2π). So RMF ≈ (mass × acceleration × velocity) ÷ (2π). Plugging in the numbers: 7 × 3 × 5 = 105. Divide by 2π (≈ 6.283): 105 ÷ 6.283 ≈ 16.7. That’s about 17, and among the given options, 16 is the closest approximation. If you multiplied by 2π instead, you’d get a much larger number (around 660), which isn’t one of the options.
