What is Newton's law of universal gravitation?
2 answers:
Newton's law of universal gravitation, introduced by Sir Issac Newton, states that an object entices every other object in the universe with a force or pressure that is straightly proportional to the product of their masses and reversely proportional to the square of the distance between them.
In simple expression it is a law declaring that any two masses stimulate each other with a force equal to a persistent of gravitation multiplied by the outcome of the two masses and divided by the square of the distance across the space separating between the two objects or regions.

Answer:
So coefficient of kinetic friction will be equal to 0.4081
Explanation:
We have given mass of the block m = 0.5 kg
The spring is compressed by length x = 0.2 m
Spring constant of the sprig k = 100 N/m
Blocks moves a horizontal distance of s = 1 m
Work done in stretching the spring is equal to
This energy will be equal to kinetic energy of the block
And this kinetic energy must be equal to work done by the frictional force
So
So coefficient of kinetic friction will be equal to 0.4081
