Answer
$P=400(10^3)tW$
Work Step by Step
The power generated can be determined as follows:
$a=\frac{T}{m}$
$\implies a=\frac{20\times 10^3}{m}=20m/s^2$
According to the equations of kinematics
$v=v_{\circ}+at$
$\implies v=0+20t$
$\implies v=20tm/s$
Now $P=F\cdot v=T\cdot v$
We plug in the known values to obtian:
$P=(20\times 10^3)(20t)$
$\implies P=400(10^3)tW$
