What aperture do I need for a GN 100 flash at ISO 400 and 5 meters away?

You should use an aperture of f/8.

What power fraction is needed for a GN 36 flash at ISO 100, distance 3m, and f/5.6?

The required power level is 1/2.

Will a flash duration of 0.0001s freeze a subject moving at 2m/s across a 0.01m frame area?

Yes, the motion will be frozen.

Use the `calculate_required_t_stop` tool by providing your flash's guide number, current ISO, and distance to the subject. Tools available: `your_tool_name`.
