Answer:
The gravitational force is significantly constant.
Explanation:
The gravitational force is expressed as:
F= G*M*m/d^2
G= Gravitational constant
M= in this case it is the mass of the planet
m= mass of the rock
d= distance of the rocks from the ground (suppose both at the same height for better comparison)
At the same time, we know that the force that each rock experiences is equal to the product of the mass due to acceleration:
F=m*a
We can match both expressions for F:
G*M*m/d^2 = m*a
we simplify m, and we obtain that the acceleration is independent of the mass of the attracted bodies:
a= G*M/d^2
The work to stretch a spring from its rest position is
(1/2) (spring constant) (distance of the stretch)²
E = 1/2 k x² .
You said it takes 1700 joules to stretch the spring 3 meters from its rest position, so we can write
1700 joules = 1/2 k (3m)²
1 joule = 1 newton-meter
1700 N-m = 1/2 k (3m)²
Multiply each side by 2: 3400 N-m = k · 9m²
Divide each side by 9m² k = 3400 N-m / 9m²
= (377 and 7/9) newton per meter
