Answer 2

$\huge { \green {\boxed{ \purple { \boxed{\red {\boxed{\orange{\boxed{\red {\underline{ \mathscr \pink{A}}{ \underline{ \mathbb \green{n}}}{ \underline{ \mathfrak \red{s}}}{ \underline{ \mathtt \blue{w}}} {\underline{ \bold{e}}}{ \underline{ \mathscr \purple{r}}}}}}}}}}}}}$

about 11.2 km/s

On the surface of the Earth, the escape velocity is about 11.2 km/s, which is approximately 33 times the speed of sound (Mach 33) and several times the muzzle velocity of a rifle bullet (up to 1.7 km/s).
