The loaded cab of an elevator has a mass of 3.0*103^ kg and moves 245 m up the shaft in 23 s at constant speed. At what average rate does the force from the cable do work on the cab? (in kW)(adsbygoogle = window.adsbygoogle || []).push({});

I know that Power= Work/Time or Change in Energy/Time

I did this but it was wrong:

(1/2)(3.0*10^3)(245/23)^2 divided by 23

=7400000kW

Can someone tell me what i did wrong. I think I calculated the work wrong, but I don't know what else too do.
