Question

Whats is the best formular used in finding escape velocity and how do i use it.

Answer 1

Answer:

v escape = √2Gm/R

or √2gr

where g =Gm÷R*2

Answer 2

Answer:

Ve=$\sqrt{2gR}$

Explanation:

g is acceleration due to gravity

g is also = GM/$R^{2}$

therefore ve =$\sqrt{2GM/R}$

G = 6.7 * 10^-11

R= 6400 km

for earth it’s value is 11.2km/s
