Answer:
Acceleration due to gravity will be
.
Explanation:
We can use the gravitational force equation:

The F is equal to the weight of the astronaut, so we will have:


- M(e) is the mass of the earth

- R is the radius of the earth

- G is the gravitational constant

But the distance between the astronaut and the center of the earth is 2R, then we have:
Therefore the acceleration due to gravity will be
.

Answer:
Explanation:
m= 2000 kg
u= 10 m/s
v=0
f= 5000 N
a= f/m=-5000/2000=2.5 m/s^2
2 as= v^2-u^2
2*-2.5*s=0-100
s=20 m
