Question

Calculate the minimum velocity required by spacecraft to escape the earth's gravitational force.
What I need is the calculation of the values to get to the answer.
Velocity (esc) = 2GM/R the whole under root.​

Answer 1

Answer:

11.2 km/s

Explanation:

2GM/R =[ 2 × 6.67 ×10^(-11) × 6×10^(24)kg]÷6.4 ×10^(6)

= 11.2 km/s

here, M is mass of Earth,

R is radius of Earth,

G is universal gravitational constant.

V(esc) = 11.2 km/s.
