Alberto was able to walk away from the accident because he had his seat belt on according to Newton's first law.

According to Newtons's first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by an external, unbalanced force. This law is the reason why a passenger quickly moves forward when a car stops suddenly.

Alberto was able to walk away from the accident because he had his seat belt on which prevented him from being thrown out of the windscreen. The momentum and kinetic energy of the car is not conserved because the car sticks with the tree.

Explanation:

Given that Alberto is on his daily commute. While texting, his car veers of the road and hits a tree, coming to a complete halt. As state law required, he was wearing a seatbelt, and walked away from the accident uninjured.

To use the concepts of momentum, kinetic energy, and force to explain why Alberto was able to walk away from the accident,

According to the Newton's second law of motion, the rate of the change in momentum is proportional to the force applied. that is,

F = ma

where

F = the force that caused the car to accelerate

m = mass of the car

a = the acceleration of the car.

As the car accelerated, the kinetic energy produced caused the car to hit the tree.

But according to the Newton's third law of motion, which state that;

in every action, there will be equal and opposite reaction.

The seat belt provided the reaction opposite to the action produced by the force. Which eventually halt the Kinetic energy of the person and prevented him from being getting injured.
