Vectors represent relationships according to the position, velocity, and acceleration (of a moving object).
Because so many physical things are vectors, you have to be able to add and subtract them, helping you understand how the world around you behaves.
I had to do some research (I was never good with physics) so if you have a couple questions, I will try to explain.

Answer:
The value of spring constant is 266.01 
Explanation:
Given:
Mass of pellet 
kg
Height difference of pellet rise 
m
Spring compression 
m
From energy conservation law,
Spring potential energy is stored into potential energy,
Where 
spring constant, 
Therefore, the value of spring constant is 266.01
Normal force for the rock because that makes an object stable at its position.
static friction because micro-welts hold its particle on its position so it doesn't change in position by a potential energy. Gravity makes it stay on the ground because its force attraction between an object and the earth.
Hope this helps <span />
