The gravitational force acting between them is 
Data given;
- M1 = 45kg
- M2 = 11kg
- r = 2.0m
- G =

To solve this question, we need to apply gravitational force or energy formula.
<h3>Gravitational Force</h3>
This states that the force of attraction between two bodies is equal to the product of their bodies and inversely proportional to the square of their distance apart.
Mathematically;

let's substitute the values and solve

Answer:
A. 500 N
Explanation:
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (50 m/s − 20 m/s) / 3 s
a = 10 m/s²
Force is mass times acceleration.
F = ma
F = (50 kg) (10 m/s²)
F = 500 N
