The frictional force is 
Explanation:
From the question we are told that
The coefficient of kinetic force is μk = 0.35
The normal force felt by the puck is 
Generally the frictional force that acts on the puck is mathematically represented as

=> 
=> 
I believe it is A, if I am remembering correctly from my last semester class.
The third law<span> states that for every action (force) in nature there is an equal and opposite reaction.

Explanation:
Systems thinking is an outlook to integration that believes that the components of any system will function in a different manner when they are made to function separately from the other components of the system or are separated from the environment of the system.
It is therefore, the ability for the modelling of the system's component, to make the components connection to the input/output in order to reflect the dynamics and built-up of a system.
