Answer: M = 1797.75 kg
Explanation:
given parameters are;
speed V = 26.7 M/S.
momentum P = 4.8×10^4 KGM/S.
What was the mass of the V. A-3?
Momentum P is the product of mass and velocity. That is, P = MV
Substitute V and P into the formula
4.8×10^4 = 26.7 × M
Make M the subject of formula
M = 4.8×10^4/ 26.7
M = 1797.75 kg
Therefore, the mass of the V. A-3 was 1797.75 kg
The object's mass is around 69.592 kg

Answer:
The gravitational force between them increases by a factor of 4
Explanation:
Gravitational force is a force of attraction between two objects with masses M and m which are separated by a distance R. It is given mathematically as:
Fg = GMm/R²
Where G = Gravitational constant.
If the distance between their centers, R, decreases by a factor of 2, then it means the new distance between their centers is:
r = R/2
Hence,the gravitational force becomes:
Fg = GMm/r²
Fg = GMm/(R/2)²
Fg = GMm/(R²/4)
Fg = 4GMm/R²
Hence,the gravitational force increases by a factor of 4.
