Gordon bennet. Who does calculations in these barbaric units?

1100lb = 500kg - 5kN

5fps = 1.5m/s

5kN * 1.5m/s =7.5kW = 10hp

OK, more or less!

LOL ... I guess so ...

James Gordon Bennet II, 1841 - 1918 is the man referred to, and was
quite a colourful character. One of his many reported exploits was an
incident where he flew an aeroplane through an open barn. The surprised
onlookers were supposed to have said 'That was Gordon Bennett!', and
hence onward to the current shortened phrase. Became popular again
during the 1980s but is again falling out of use.
