Newton's second law deals with mass and force as it relates to acceleration. Acceleration down the hill is the main part of skiing, which skiers can affect by changing their mass or the force they use to push themselves down the hill.

You fall as hard as you jumped when you don't stick the landing.
It affects sky divers because the closer you are to the ground the faster you go.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Newton's second law of motion (F=ma) explains how a force acting on an object will cause it to accelerate. In terms of vehicle safety, this law is crucial because it helps engineers design vehicles with the right balance of mass and acceleration to ensure they can stop or maneuver safely in various driving conditions. Understanding this law also helps in designing safety features like airbags and seatbelts to protect occupants in case of a collision.

This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
the second law
The clue is in the question.
The squid moving forward by shooting water out behind it illustrates Newton's third law: for every action, there is an equal and opposite reaction. As the squid expels water backwards with force, an equal force propels the squid forward, allowing it to swim.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
Every single object that exists obeys ALL of Newtons Laws
