Answer
2,374 m/s
Work Step by Step
$v = \sqrt {2Gm/r}$
mass = $7.35*10^{22}$ kg
radius = $1.74 *10^{6}$ m
G = $6.67*10^{-11}$ $m^3/kg*s^2$
$v = \sqrt {2*6.67*10^{-11}*7.35*10^{22}/1.74*10^6}$
$v = \sqrt {2*6.67*10^{11}*7.35/1.74*10^6}$
$v = \sqrt {2*6.67*10^5*7.35/1.74}$
$v = \sqrt {2*6.67*10^5*7.35/1.74}$
$v = \sqrt {98.049*10^5/1.74}$
$v = \sqrt {56.35*10^5}$
$v = \sqrt {56.35*10^5}$
$v = \sqrt {5635000}$
$v = 2373.8155$
