$Mass = 200kg$ -- mass of tub

$Energy = 200,000J$

$Time = 80s$

Required

Determine the amount of power needed

Power is calculated as thus:

$Power = \frac{Energy}{Time}$

Substitute values for Energy and Time

$Power = \frac{200,000J}{80s}$

$Power = 2500W$

Divide by 1000 to convert to kW (kilowatt)

$Power = 2.5kW$
