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 forces 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.
