I found some missing information about this problem online. We are given the force:

Power is defined as the rate of doing work.
This is the formula:

Where P is power, W is work.
Work is defined as:

F is the force and r is the displacement.
If we assume that force is not changing (it's constant) with time we get:

Keep in mind that both force and velocity are vectors, so we have to multiply each component separately.
Finally, we get:
Two Factors That Affect How Much Gravity Is on an Object. Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object.
Answer:
Gravity
Explanation:
The answer is gravity because when the 3 masses were hung from the spring, gravity pulled the spring towards the ground.
Answer:
18 times
Explanation:
According to the security purposes which is set under the rules and regulation OSHA, which describes all the rights to the worker.
In the boom hoist receiving system all the sheaves which are used should have a pitch diameter of rope not less than 18 times the diameter of the nominal rope which is used.
