Equations used to solve inputs

NOTES
1.
The speed of an object thrown upward is decreasing until it reaches a speed of 0 m/s, at this point it starts to fall back to earth with an acceleration of g.

The gravity

Two masses in the space are generating attraction force between them due to gravity in the amount of
Gravity F=(G M m)/r^2

G − universal gravity value equal to:

Universal gravity value G=6.672 × 10^(-11) (N m^2)/〖kg〗^2
r − the distance between masses centers.
M, m − two masses in gravity field.

The gravity field is engulfing the entire space around the masses so a third mass will influence the total gravity field of all the masses. Gravity is a vector with direction to the forces balance.
