How much power does chuck norris have in a roundhouse kick? how does 2,,500 k of work in 5 seconds when he spins and kicks a bad guy to save the planet from immediate destruction.
sorry my science teacher makes up weird problems

That's a wonderful problem !  If it was just dry numbers and formulas,
people would come back and ask "How can this be used in the real
world ?"  Well, now you know !

There's a bit of a problem with the problem ... the quantity of work.
' k ' doesn't look like any usual unit of work.  So I'll have to make up
a unit of work, and then solve the problem that I made up.

I'm going to ignore the little ' k ', and assume that the 2,500 is the
normal metric unit of work ... "joules".

           Power  =  (work) / (time)

                       = (2,500 joules) / (5 sec)

                       =  500 joule/sec  =  500 watts .

There's your answer.  I'm pleased to have been involved
in saving our planet from immediate destruction, and I like
your teacher.
