#### Answer

$P=8.32\times 10^3hp$

#### Work Step by Step

We can determine the required power as follows:
$v=(600mi/h)(\frac{5280ft/mi}{3600s/h})=880ft/s$
Now $P=Fv=Tv$
We plug in the known values to obtain:
$P=(5200)(800)$
$\implies P=4576000lb\cdot ft/s\frac{1}{550}$
$\implies P=8.32\times 10^3hp$
