Hi there
I'm writing a problem sheet for a class that I teach and I'm trying to use as many real world examples as I can. I'm writing simple questions about the power output of engines that are moving vehicles at constant speeds. I've used cars and boats, but now I want to use aircraft.
From information on the internet I've researched that a Boeing 747 has a max thrust of around 1184 kN and a max speed of 274 m/s. This gives me a max power output of 324 MW. Err, I know this is a maximum value and all, but I don't believe the result. To my simple physics teacher's mind it seems far too big. Can someone give me a hint if my value is reasonable?
