Answer
$K.E$= $1.82\times10^{13}J$
Work Step by Step
As we know that
$K.E$=$\frac{1}{2}$$m$$v^{2}$
Putting the values, we get
$K.E$=$\frac{1}{2}(2.9\times10^5)(11.2\times10^3)^2$
$K.E$=$1.45\times10^{5}\times11.2\times11.2\times10^{6}$
$K.E$=$181.888\times10^{11}$
$K.E$=$1.81888\times10^{2}\times10^{11}$
Or after rounding it off, we get
$K.E$=$1.82\times10^{13}J$
