Hello, can you can tell me if this is correct? I thought the height would turn out(adsbygoogle = window.adsbygoogle || []).push({});

close to where satellites orbit, but it comes out to about 5.5 million miles away!

I was very surprised by this, that's about 20 times further than the moon.

Here's what I used

Escape velocity: Ve = sqrt(2GM/r)

Earth mass: 5.97x10^24 kg

Gravitation constant: 6.67x10^-11 N(m/kg)^2

(Ve=) Handgun bullet speed: 300 m/s

regards,

Walter
